摘要
随着高层建筑的大量兴建,与之配套的地下室也越挖越深,继而出现了地下室底板和外墙渗漏现象,造成了巨大的经济损失和社会影响。以贵州某高层建筑为例,在介绍场地的工程地质及水文地质条件的基础上,通过现场抽水试验过程中的水位观测,认为安装在地下室的自动泵长期抽出的水没有排到场地以外的城市排水系统中,而是在肥槽中不断循环,肥槽中水位长期高于地下水位,其积水又渗入地下室,是造成地下室底板破裂的主要原因。经过将大气降水、施工用水及工人生活用水等及时排到场外的城市排水系统中等措施,最终解决了基坑肥槽积水问题,为以后施工相似工程具有一定的借鉴作用。
Along with the large number of high-rise buildings constructed, compatible basements getting deeper, then leakage phenomenon of basement floor and external wall has presented and caused huge economic loses and social impacts. Taking a high-rise building in Guizhou as an example, based on site engineering geological and hydrogeological conditions introduction, combined with water level observation during site pumping test process, considered that the pumped water from an automatic pump in the basement have not been pumped into urban sewerage and drainage system over the years, but rather recirculated within foundation pit extension （fertilizer tank）. Water level in the extension is higher than groundwater level age-long; the ponding seeping into basement is the main causation of basement floor fracturing. After measures to drain atmospheric water, construction water and workers living water into outside urban sewerage and drainage system in due course, finally, the issue of ponding in foundation pit extension is settled. The study can be a reference for construction of similar engineering henceforth.
