摘要
结合工程实例,介绍爆破法在冻土基坑开挖中的应用。对基坑周边采用光面爆破控制其平整性。此次爆破,方案、参数选取合理,爆破效果良好。爆破的结果表明:爆破法开挖冻土基坑效率高,施工简便。基坑周边采用光面爆破不但可获得光滑平整的壁面,且不破坏光面冻土的强度,具有明显的经济效益。
Combined with an engineering case, the paper introduces the application of blasting method in foundation pit excavation of frozen soil, and adopts the smooth blasting to control the level around the foundation pit. The project and parameters of this blasting are reasonable, and the effect is good. The result indicates that blasting method can increase excavating efficiency and facilitate construction. Using smooth blasting, we can not only obtain smooth plane, but also not destroy the intension of smooth-plane frozen soil. It has obvious economic result.
