摘要
新建铁路成都至自贡线土建预留段小里程基坑采用放坡开挖的方式,基坑深10 m,边坡为回填土,因土质不均、支护工序较多,故进度偏慢且环保无法满足要求。为此,工程采用了可回收利用的边坡支护技术,相比传统技术,其社会和经济效益明显,为后续类似工程的建设起到了参考和借鉴作用。
The foundation pit of the newly-built railway from Chengdu to Zigong adopts the construction approach of slope excavation.The foundation pit is 10 m deep and the side slope adopts backfill soil.The construction progress is slow and the environmental protection cannot meet the requirements due to the inhomogeneous soil and cumbersome support procedures.To this end,the project adopts recyclable slope support technology,which has both social and economic benefits compared with the traditional technology.Such technology can provide references for the subsequent construction of similar projects.
