摘要
沉桩对周围建筑物的影响是工程界的研究热点,根据浙江某码头改造沉桩可能产生的施工风险,分析了监测方案的考虑因素,并对监测方案设计思路及合理性进行了研究,创造性地将孔隙水压力计与三向振动速度传感器同孔埋设,极大节约了施工时间和成本;同时对监测数据进行了分析,保障了沉桩周围建筑物的安全,监测方案的设计和应用可供类似工程借鉴。
Effect of pile-driving on adjacent construction has always been an important subject for engineering researches.According to the possible construction risk of the pile-driving reconstruction project of a wharf in Zhejiang, we analyzed the considering factors of the monitoring scheme, and studied the design vision and the legitimacy. The scheme creatively combines the PPT(Pore water Pressure Translator) and the 3-way vibration velocity sensor in one hole, which saves the cost and time immensely. We also analyzed the monitoring data, ensured the safety of surrounding buildings. The design and application of this monitoring scheme can serve as reference for relative engineering projects.
