灌浆法在公路桥梁隧道施工中的应用

公路桥梁隧道施工中常出现裂缝、砌石松动、砌浆唯落等问题,利用灌浆法对公路桥梁隧道基础进行加固能够有效改善上述问题,并显著提升墩台基础的承载能力.结合公路桥梁隧道工程实例,对灌浆法的加固原理,设计标准进行阐述,并提出具体的施工方法.

Grouting Method in Construction of Highway Bridges and Tunnels

There are some problems of cracks, loose, masonry cement off in highway tunnel construction. The highway bridge and tunnel foundation reinforcement can effectively improve the problems above with grouting method, and significantly enhance the carrying capacity of the pier foundation. Combined with the example of highway bridge and tunnel engineering, reinforcement principle of grouting method and design standards are described, and concrete construction methods are put forward.
