五湾重力式码头位于广东深圳蛇口工业区,建成后有较大的水平及垂直位移,两年后重力式墙身基础外移,至使码头倾倒,范围约48m。本文用离心模拟技术和稳定分析计算等手段研究出此重力式码头的坍塌机理,证明此种破坏形式主要是由地基土质软弱、设计时抗滑安全系数过低所造成,为修复此工程提供了依据。一、码头坍塌前后工程概况五湾码头为明基床空心方块重力式混凝土
Located in Shekou Industrial Zone, Shenzhen, Guangdong Province, the five-bay gravity wharf has a large horizontal and vertical displacement when completed. After two years, the gravity-based wall base relocated to dump the wharf at an area of about 48m. In this paper, the collapse mechanism of the gravity wharf is studied by means of centrifugal simulation and stability analysis and calculation. It is proved that the failure mode is mainly caused by the weak soil foundation and the too low safety coefficient of anti-slide during design, in accordance with. First, the terminal before and after the collapse of the project overview Wuwan pier BenQ bed hollow square gravity concrete
