摘要
重力式码头方块墙施工过程中,常采用高低脚龙门吊吊装方块,其中门吊的柔性支腿设置于边坡平台,刚性支腿设置于港池内。由于门吊自身荷载较大,将对边坡的安全稳定造成影响。为了保证施工安全,对高低脚龙门吊的荷载进行简化,采用Geo-Slope软件的Morgenstern-Price及Bishop两种方法,对边坡在无门吊及有门吊两种工况下的抗滑安全系数进行了稳定验算,其结果满足要求。
Gantry crane is often used in construction of block lifting of gravity wharf. One outrigger of gantry crane is located on the slope berm,which will effect the safety of slope. Geo-Slope software,Morgenstern-Price Method and Bishop Method are used to analyse the safety of slope under the loads of gantry crane.
