高危区域土石方泄能槽的爆破施工技术研究

Study on Blasting Construction Technology of Earth-rock Energy Discharge Chute in High-risk Area

为避免高危区域土石方爆破时,开挖爆破方式不当而对坡脚处居民生命财产安全造成威胁,需改善爆破效果、降低施工成本、降低安全风险,做好土石方爆破施工技术控制。通过对重庆市嘉陵江磁井段防洪护岸综合整治工程项目爆破施工的实践与总结,提炼出应用于高危区域土石方泄能槽爆破施工工艺,并对其原理和优势进行了分析、说明,从而为其他类似工程提供一些工程经验。

In order to avoid the threat to the life and property safety of residents at the slope toe caused by improper excavation blasting in high-risk area,it is necessary to improve the blasting effect,reduce the construction cost,reduce the safety risk,and achieve good technical control of earth-rock blasting construction.Through the practice and summary of blasting construction of Cijing section of Jialing River in Chongqing,the blasting construction technology applied to earth-rock energy discharge chute in high-risk areas is extracted,and its principle and advantages are analyzed and explained,so as to provide some engineering experience for other similar projects.
