摘要
根据南京某泵房基坑工程的地质特点和具体情况,对其进行监测并设置预警值,通过对监测结果进行分析,得出了基坑周边地表的沉降量、支护桩桩身基坑方向的水平侧向位移与开挖深度的关系,对选择合理、经济的支护方案,具有一定的理论和实际应用价值.
Based on the geological characteristics and specific circumstances of a pumping station excavation in Nanjing, the monitoring with presetting alarm figure is performed. Through analyzing the monitoring results, the settlement around foundation surface and the relationship between the horizontal lateral displacement and the ex- cavation depth of the supporting pile are obtained, which is applicable to the choice of reasonable and economical support program in both theory and practice.
