杭温铁路地形陡峻地段深路堑开挖施工技术分析

Excavation Technology of Deep Cutting in Steep Terrain of Hangzhou-Wenzhou Railway

以新建杭温铁路低山地段深路堑工程为例,结合现场实际情况,从工程工况、施工方案与流程、变形监测方面对土石组合地质条件下深路堑开挖施工技术进行了介绍,同时从爆破参数设计、起爆、装药等方面对石质路堑爆破开挖做了详细分析,最后探讨了施工中需要注意的问题,以期为今后相关的工作提供参考。

Taking the deep cutting project in the low mountain section of the newly built Hangzhou w enzhou Railway as an example,combined with the actual situation of the site,the construction technology of deep cutting excavation under the combined geological conditions of earth and rock is introduced from the aspects of engineering conditions,construction scheme and process,and deformation tmonitoring.At the same time,the blasting excavation of stone cutting is analyzed in detail from the aspects of blasting parameter design,initiation,charging,etc.Finally,the problems that need attention in the construction are discussed,to provide reference for future related work.
