近年来,在黔中地区,一些地下室工程在施工过程中,出现突然渗水,不仅使地下室底板、地梁变形破坏,且涌水量要超出勘察时预测值的几倍乃至几十倍。本文对3个较典型的深基坑(地下室)渗水案例分析后认为,勘察、分析基坑岩溶含水层渗流特征是保证抗浮水位和涌水量预测的关键。
In recent years, in the middle of Guizhou Province, some basement projects suddenly seeped water during the construction process, which not only deform and destroy the basement floor and the ground beams, but also infiltrate several times or even tens of times more than predicted values at the time of survey. In this paper, case analysis of three typical deep foundation pit (basement) seepage cases is conducted. It is considered that it is crucial to investigate and analyze the seepage characteristics of the karst aquifer in the foundation pit to ensure the anti-floating water level and water inflow.
