  1. Combining achievements in past scientific research, this thesis summarizes some problems in the process of decreasing water, the problems contains : important parameters such as percolation coefficient, interfering radius etc ; designers get parameters from their experience and make their choice of limited prospecting materials too simply, because of the limits, designer ca n ' t make quantitative analysis on groundwater ; differences on breakwater effect of setting water - tight screen is still existed, although research evolvement in this field is done ; they ca n ' t grasp the hydrogeology parameters accurately in that it influences rightness of designing in deep excavation water - decreasing

    本文結合以往的研究成果,總結了降水過程中存在的一些問題,主要包括:重要設計參數,如地層滲透性、基坑降水影響半徑等,設計中僅從個人經驗出發取值,對有限的勘探資料進行取捨和過分地簡化。這些局限使設計者不能對地下水進行科學的定量分析,盲目性較大;深基坑降低承壓水引起的周邊地面沉降的研究雖已取得很大的進展,但是一些主要問題仍未解決,對防滲帷幕的實際擋水效果存在不同看法;對於弱透水層的水文地質參數一直難以準確把握,影響了深基坑降水設計的正確性。
