摘要
依托典型的道路软土路基滑塌工程案例,文章分析了软土路基填筑施工过程中路基滑塌的失稳诱因,提出了反压护道+土工格栅、全断面卸载土方+砂桩排水堆载预压、部分卸载土方+全断面素混凝土桩、部分卸载土方+半断面素混凝土桩等4种不同的软基滑塌处治技术方案,从施工安全、工期、工程造价、环境保护、征地等方面进行方案比选,建议采用"部分卸载土方+全断面素混凝土桩"的处治技术,并提出相应的软土路基施工注意事项,为类似道路软基的设计、施工及失稳处治方案提供参考与借鉴。
According to the engineering case soft foundation collapse on road,the collapse cause were analyzed in the of filling construction,and four different treatment plans were put forward,including“back berm&geotechnical grille”,“whole section unloading earthwork&sand pile preloading”,“partial unloading earthwork&plain concrete pile”etc.Comparing from construction safety,engineering cost,environmental protection and land expropriation,the cheme“partial unloading earthwork&plain concrete pile”was suggested and the matters of construction attention were precautioned.This achievement can provide technology reference and experience for the design and construction of soft construction.
