Problems solved by technology
A wave direction and orientation verification device of a wave buoy is also used, which can measure the wave direction, but its measurement elements are relatively single and its structure is relatively complicated
From the above, it can be seen that the equipment and methods for measuring wave elements in the prior art have the following problems: the measuring equipment is expensive and the measurement cost is high; the buoy system is difficult to maintain and affect on-site construction; elements and tide levels for comprehensive measurements

Embodiment Construction
[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0047] see figure 1 As shown, the embodiment of the present invention provides a wave element and a tide level measurement method in the sea area of a cross-sea bridge based on wave pressure, and the specific steps are as follows:
[0048]Step 1. Select a test point in the construction sea area. The wave propagation direction at the test point is not blocked by the construction temporary structure. Set 24 wave pressure sensors 3 at equal intervals around the outer surface of the steel pipe pile 1 located in the test point. The angle between the adjacent wave pressure sensors 3 is 15°, and the wave pressure sensors 3 are located at 2-4 meters below the low tide level average water level;
[0049] see figure 2 and image 3 As shown, in this embodiment, the outer surface of the steel pipe pile 1 is provided with a mounting plate 2, which is...

The invention discloses a wave pressure based method for measuring wave parameters and tide level of a sea-spanning bridge construction sea area. The method comprises specific steps as follows: step 1, a test point is selected in the construction sea area, a plurality of wave pressure sensors are annularly arranged on the outer surface of a steel pipe pile located in the test point at intervals, and the wave pressure sensors are located in the position 2-4 m lower than a mean water level of the low tide level; step 2, a wave pressure time travel curve corresponding to each wave pressure sensor is generated according to wave pressure values collected by the wave pressure sensor; step 3, one wave pressure sensor with the maximum wave pressure value in a certain time period is selected as a reference wave pressure sensor, and the wave pressure time-travel curve of the reference wave pressure sensor is taken as a reference wave pressure time-travel curve; step 4, the wave parameters and the tide level are calculated according to the reference wave pressure time-travel curve. The structure is simple, and the method is used for comprehensively measuring the wave parameters and the tide level.
Description
technical field [0001] The invention relates to the technical field of wave elements and tide level measurement, in particular to a method for measuring wave elements and tide levels in sea areas of cross-sea bridges based on wave pressure. Background technique [0002] The construction of cross-sea bridges needs to face complex marine environments. Environmental loads such as strong winds, waves, and current speeds have an important impact on the construction of bridges, and even play a decisive factor. In actual engineering, the relevant regulations on wave force in the "Hydrological Specifications for Seaports" (JTS 145-2-2013) are usually referred to as the basis for calculation, and wave elements are an important part of wave force calculation. [0003] The current wave element test generally uses an air-mediated ultrasonic wave meter, which can test the wave height and period of the wave, but cannot measure the direction and tide level of the wave. A spherical water s...
