快速法基桩静载试验在常熟区域的适用性研究

Research on the Applicability of Quick Method for Pile Static Load Test in Changshu Region

对比分析了常熟不同土质区域的基桩快速、慢速维持荷载法试验结果,发现快慢法试验所得曲线性状均能反映桩在荷载作用下的沉降特征,但在淤泥层厚的东北部区域测得的沉降差异大,得出快速法基桩静载试验适用于常熟西北部、南部,不太适用于东北部。

A comparative analysis was conducted on the results of fast and slow maintenance load tests on foundation piles in different soil regions of Changshu.It was found that the curve characteristics obtained from the fast and slow method tests can reflect the settlement characteristics of piles under load.However,the settlement differences measured in the northeast region with thick silt layers are large.It was concluded that the fast method static load test for foundation piles is suitable for the northwest and south of Changshu,but not very suitable for the northeast region.
