Anti-floating water level value taking method in which long-observing water levels and historical rainfall in latest 3-5 years are utilized

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...
