摘要
结合浃里陈大桥桥头试验段的施工工艺 ,对真空联合堆载预压加固软基施工过程必须做好的各项密封施工步骤进行了探讨与研究 ,包括密封膜的质量 ,铺膜前的工作 ,水位管与分层管的出膜工作 。
According to the construction technology of the piers of Jialichen bridge,this paper primarily studied the construction process of reinforcing soft foundation by preloading in vacuum.The quality of membrane,prior works,membrane laying out,tube's pulling out from membrane,peripheral trench and embankment on membrane were discussed.The results show that considerable improvement can be achieved by sealing.
