摘要
鉴于乡道Y147线K5+350-K5+402段路基发生严重塌方,建设单位提出两个修复方案:第一个方案采用片石砼重力式挡土墙和三维网植草护坡的技术措施;第二个方案采用加筋格宾挡土墙和麦克护垫植草护坡的技术措施。通过对以上两个技术方案的比选,认为第二个方案在安全性、经济性和适应施工环境等方面优于第一个方案,进而经过技术可行性研究,认为第二个方案在技术上是可行的。建设单位最终采用了第二个方案修复塌方路基,并取得良好效果,为加筋格宾挡土墙何麦克护垫植草护坡技术在广东粤西地区推广提供有益的借鉴作用。
In view of the serious collapse of the roadbed in section K5+350~K5+402 of the Y147 rural road,the construction unit has put forward two repair schemes:the first one is to adopt gravel concrete gravity retaining wall and three-dimensional mesh grass slope protection technical measures;the second one is to adopt reinforced Terramesh retaining wall and Mike pads grass slope protection technical measures.Through the comparison and selection of the above two technical schemes,it is considered that the second scheme is superior to the first one in safety,economy and adaptability to construction environment.Then,through technical feasibility study,it is considered that the second scheme is technically feasible.The construction unit finally adopted the second scheme to repair the roadbed collapse,and achieved good results,which provided a useful reference for the promotion of reinforced Terramesh retaining wall and Mike pads grass slope protection technology inWestern Guangdong.
