摘要
论述了在Ｑ３黄土地层内两个相同外尺寸，按１２比例尺进行的桥梁实体挖井基础和连续墙挖井基础的模型试验及有限元分析。结果表明，连续墙基础内侧土体不提供竖向摩擦力和水平抗力，在设计这种基础时可按空心基础建立计算模型。同时还介绍了国内第一个铁路桥梁连续墙挖井基础工程实例。
The results have shown that vertical friction force and horizontal resistance did not appear in the soil column inside the diaphragm wall type digging well foundation.The calculating model of a hollow foundation was established in designing this foundation,which hoppened to be in conformity with the research results.A history case of the first diaphragm wall type digging well foundation of railway bridge in China is given.
