Wind measurement data wind speed correction method based on probability distribution transfer

The invention discloses a wind measurement data wind speed correction method based on probability distribution transfer. The method comprises the steps that firstly, statistical description is carried out on wind speed through a Weibull distribution function; then, the wind speed probability distribution estimated values of an actual measurement year long-time meteorological station, an actual measurement year wind field observation station, a representative year long-time meteorological station and a representative year wind field observation station corresponding to the ith sequence number are respectively calculated; finally, the wind speed is actually measured by the actual measurement year wind field observation station corresponding to the ith sequence number according to hourly wind speed data and the probability distribution estimated values, and the correction wind speed of the representative year wind field observation station corresponding to the ith sequence number is calculated through a probability distribution identical difference value transfer method or a probability distribution identical multiple proportion transfer method. According to the probability distribution transfer method for wind speed correction, the defect that common correlation coefficients in an existing correlation analysis class method are too low and have to be used for correction is overcome, and the method can be suitable for wind speed correction under the conditions that the distance of project sites of an inshore or offshore wind plant and the like and a long-time meteorological bench-mark station is too far or the correlation of the existing method is poor.

Detection method for assembled floor-board water absorption expansivity

The invention discloses a detection method of water absorption expansion rate of assembled floors, comprising the following steps: 1) assembling four floors wherein the middle two floors are arranged in vertical line shape and another two floors are arranged at the two horizontal sides of the two middle floors, the four floors are in the shape of a Chinese character 'zhong'; 2)respectively making five bench marks respectively in the middle point of the assembling point of the middle two floors, respectively arranged at the upper and lower 1/4 floor-length position at the horizontal sides of the two middle floors and measuring the floor thickness h1 of the five mark points; 3) covering the five bench marks by a water absorption sponge for two hours and measuring the floor thickness h1 of the five mark points h2, and then calculating the floor thickness water absorption relative expansion degree, if one bench point is larger or equal to 3%, the floor of the batch is not qualified. The detection method simulates the water absorption expansion process of the composite floor to constitute the calculation method capable of more practically characterizing the relative water absorption expansion degree of the finished composite floor and the qualification criterion standard.

Concrete bench mark monument for mounting displacement sensor and elevation observing and calculating method thereof

ActiveCN107063178AReduce the frequency of joint testingSolving elevation observation problemsHeight/levelling measurementPermanant marksBench markingStructural engineering
The invention discloses a concrete bench mark monument for mounting a displacement sensor and an elevation observing and calculating method thereof. The displacement sensor is arranged in the conventional concrete bench mark monument, and is connected with a drill hole anchoring end with a certain design depth through a connecting rod. When the concrete bench mark monument on the earth surface sinks, the sensor is driven to be deformed synchronously, readings of the sensor at each observing time interval are recorded through a portable reading instrument, sinking deformation of the bench mark monument relative to the anchoring end is calculated, and working starting point elevations of the bench mark monument at each observing time interval are calculated according to a connection surveying result obtained after connection surveying with a datum mark. By adopting the concrete bench mark monument, the problem of working starting point elevation observation of the bench mark monument at each observing time interval in a connection surveying period is solved, the working base point accuracy of the conventional concrete bench mark monument is increased, and working reference point and reference point connection surveying times of the bench mark monument are reduced; the concrete bench mark monument can be widely applied to settlement measurement work of engineering foundations, bases, upper structure and sites in industrial and civil buildings, municipal traffic, hydraulic engineering and the like.

Method for monitoring construction effect of foundation pit support piles below elevated high-speed railway line

ActiveCN108316364AFully play the role of monitoringPlay a monitoring roleFoundation testingBench markingGround settlement
The invention discloses a method for monitoring construction effect of foundation pit support piles below an elevated high-speed railway line. Through the method, the problem that the foundation pit monitoring criterion is not suitable for high-speed railway elevated foundation pit excavation monitoring in the prior art is solved. The method has the beneficial effect of being capable of guaranteeing safety operation of a high-speed railway elevated bridge. According to the scheme, the method for monitoring the construction effect of the foundation pit support piles below the elevated high-speed railway line comprises the following steps of (1) making monitoring plans, including layout schemes of bench marks, ground settlement monitoring points and deep soil displacement monitoring points,according to the support pile construction scheme and the situation that the support piles approach to an elevated high-speed railway foundation and conducting construction; (2) conducting monitoring;(3) analyzing monitoring data to judge the range and degree of the effect of the support pile construction process on displacement fields of soil bodies approaching to the support piles, determiningthe effect of the support pile construction process on the elevated high-speed railway foundation and then judging the effect of the support pile construction effect; and (4) giving an early warning on a construction party according to the effect, obtained by analyzing the monitoring data, of the support pile construction effect.
