| 摘 要： | 打桩施工过程会对周围建筑物及环境产生一定影响。对打桩施工的影响机理及沉桩过程模拟进行理论分析,并结合上海地区河道陆域范围内某新建厂房项目,运用孔穴扩张理论及动力有限元法,计算分析打桩施工对邻近河道的影响。动力有限元的计算结果表明,打桩施工对河道护岸影响较小,且与孔穴扩张理论的计算结论基本一致。同时提出预防和减轻打桩施工影响的设计、施工、监测措施,可为类似工程提供借鉴。

| Abstract: | The construction process of pile driving has a certain influence on surrounding buildings and environment.We make a theoretical analysis on the influence mechanism of pile driving and the simulation of pile driving process.Through a new plant project within the river land area in Shanghai,we apply hole expansion theory and the dynamic finite element method to calculate and analyze the pile construction on the adjacent riverway.The calculation results of dynamic finite element method show that the impact of pile construction on river bank is small,and is the same as hole expansion theory results.Engineering measures to prevent and mitigate the impact of piling driving are also put forward,which can provide reference for similar projects. |
