Taking into account the geometrical feature of Yue-yang Dong-ting-hu Bridge Anchorage gourd-shaped pit,the monitor points were determined reasonably,as well as the frequency of monitoring and warning value. Based on the measured data,the variation of horizontal displacement,the stress of diaphragm wall,and deformation at the top were investigated. The conclusions could be drawn as follows: The smaller diameter of gourd-shaped diaphragm wall than circular one is the reason why better dome effect exerts; the ...
