大量带有纯地下室的高层建筑,以及地下车库、下沉式广场的兴建,使抗浮问题非常突出.抗浮标准如何确定,各类规范没有明确规定.本文以北京市规划区为例,通过研究区域内浅层地下水的赋存与渗流特性,水位变化的历史过程和影响因素,通过渗流分析,提出当前解决有关问题的可能途径.

The large scale construction of highrises with portions of basements without superstructure, as well as the underguound car parking buildings in our major cities has made the anti-uplift design a very critical problem. No answer could be found in different existing codes concerning the distribution patterns of the uplifting force varying with the embedding depth of foundations or the exact values that should be taken in structure designing. Taking the comprehensive work completed recently in Beijing City as an example, the present paper brought forward a possible approach to solve this problem. Steps described in this paper including researching of the characteristics of the layered ground water conformations and seepage patterns, finding the major factors controlling the variations of time-history records of groundwater table and seepage analysis.
