| 摘 要： | 由于基坑降水引起周围土体应力的重新调整,造成基坑相邻建筑物地基不均匀沉降,情况严重则造成相邻建筑物破坏,因此对不均匀沉降量的预测具有现实意义.利用地下水动力学的非稳定流原理及土力学基本理论,介绍了基坑降水设计中引起周围地面沉降的实时预测方法,探讨了不同土层在降水过程中孔隙水压力消散对土层固结的影响,通过实例分析了公式中小同参数的取值合理性,编制了相关程序.该方法对分析、预测由于基坑降水所引起的周围地面沉降有一定参考价值.

| Abstract: | Because foundation pit dewatering causes the readjustment of stresses in soil , it brings uneven settlements and architectural damage of the building around foundation pit; accordingly ,real time prediction of land subsidence caused by foundation pit dewatering has the realistic meaning; by using the theory of unsteady well flow and basic theory of soil mechanics, the real time prediction method of land subsidence has been introduced; the rationalities of different parameters in formula have been analyzed via case study; and it has certain meaning to forecast the land subsidence around foundation pit caused by foundation pit dewatering. |

| Keywords: | dewatering of foundation pit land subsidence real time prediction of subsidence |
