Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0025] The present invention is implemented like this:

[0026] Such as Figure 1-Figure 3 Shown: According to the long-term water level and rainfall data of a site in the past 3 to 5 years, the data obtained from several observation holes are used as the calculation basis, including hole 5201010181, hole 5201010184, hole 5201010211, hole 5201030158 and hole 5201030168 .

[0027] figure 1 It is the relationship curve between groundwater level and rainfall in 5 observation holes. It can be seen from the figure that except for hole 5201030168, the groundwater level change curves of other observation holes are similar to the multi-year average rainfall curve and the maximum daily rainfall curve, and reach the maximum in June and July, and reach the maximum in December and January. min. According to ...

Abstract

The invention discloses an anti-floating water level value taking method in which long-observing water levels and historical rainfall in latest 3-5 years are utilized. The change law of the long-observing water levels along with the rainfall and a function relation are obtained according to the long-observing water levels and rainfall data of a site in latest 3-5 years, and then according to a reconnaissance inter-phase maximum water level, the reconnaissance inter-phase rainfall and the historical highest rainfall data, the highest historical water level value of the site is calculated and obtained as a water level value for prevention of up-floating of the site. According to the anti-floating water level value taking method in which the long-observing water levels and historical rainfall in latest 3-5 years are utilized, the long-observing water levels and the historical rainfall data in latest 3-5 years are utilized, through quantitative calculation, the highest historical water level value of the site is obtained as the water level value for prevention of up-floating of the site. Unreasonableness and randomness in taking the water level value for prevention of up-floating due to human factors of reconnaissance personnel are effectively overcome, a detailed and achievable calculating method of the water level for prevention of up-floating is provided, and the randomness in industry value taking is normalized.

Description

technical field [0001] The invention belongs to the technical field of anti-floating engineering of building structures, and in particular relates to a value-acquiring method for anti-floating water level using 3-5 years long-term observation water level and historical rainfall. Background technique [0002] There is no unified and specific method or formula for determining the water level of anti-floating installations in existing specifications, manuals, and documents. Most of the anti-floating water level is provided according to the highest water level measured in the survey, the highest water level in the past 3 to 5 years or the highest water level in history or even the outdoor floor elevation, or the highest water level during the on-site survey period is increased by 0 to 3m as the anti-floating water level. The highest water level is often not easy to obtain, and the anti-floating water level provided based on this is often insufficient, either too conservative, re...
