摘要
软土地基海堤施工过程中关键技术难点之一是海堤稳定性控制。恰当的稳定控制标准的确定对于保证围堤工程安全、工程进度、工程质量和控制工程费用具有重要意义。结合舟山金塘大浦口集装箱码头前期工程围堤工程施工现场监测资料,对围堤稳定控制的标准进行探讨。提出围堤施工稳定控制应以深层水平位移作为主控指标,沉降监控指标及孔压监控指标需结合水平位移速率使用。
Stability control is one of the key technical problems in seawall construction on soft ground. It is very important to determine an appropriate stability control standard for guaranteeing the safety, schedule and quality of engineering and controlling the engineering cost. Combining with the monitoring data of the seawall engineering construction site of Zhoushan Jintang Dapukou Container Terminal Earlier-stage Project, this paper conducts a discussion on the seawall stability control standard. It is pointed out that the deep-layer horizontal displacement shall be taken as the main factor of control in seawall construction stability control, and the the settlement monitoring indices and pore pressure monitoring indices shall be utilized combining with the speed of the horizontal movement.
