摘要
以某轨道交通深基坑工程中钻孔咬合桩挡土结构为背景工程,针对软土地区咬合桩成桩施工引起邻近建筑沉降这一工程问题,对咬合桩的施工工艺流程及其对地层的扰动机理进行了分析,并结合成桩过程中的工程实测资料对成桩施工引起的临近建筑沉降规律进行了分析,提出了减少咬合桩施工引起的沉降、保护周围房屋建筑的措施。
The secant piles were applied as retaining structures in deep excavation of a tunnel section with the cut and cover method. Construction of secant piles induced settlement of adjacent building in soft ground area. The procedure of the secant pile construction and its disturbance to the nearby ground were analyzed. Based on the analysis of measured data, the measures of reducing settlement induced by secant pile construction and protecting adjacent building were suggested.
