摘要
在川东地区公路工程建设过程中,易形成"土+岩"类的二元结构边坡.以川东地区某公路工程形成的二元结构边坡病害为例,通过变形过程和病害特征的分析,总结出该类边坡病害易沿二元结构分界面产生多过程牵引式滑动的特点,并在定性分析和定量计算的基础上,探讨和提出了经济有效的轻型锚杆挡墙治理措施,最后归纳出以预加固为主,因地制宜,采用工程经济性较好的轻型支挡结构的处治理念.
Abstract
In the process of highway construction in the eastern Sichuan region,it is easy to form a binary structure slope of"soil+rock"type.The article takes a binary structure slope problem formed by a high-way project in the eastern Sichuan region as an example,and through the analysis of deformation process and failure characteristics,it is concluded that this type of slope problem has the characteristic of multi-process traction sliding along the structural interface.Then,based on qualitative analysis and quantitative calculation,economic and effective measures for the treatment of lightweight anchor rod retaining walls are explored and proposed.Finally,the treatment concept including the use of pre reinforcement as the main method,the adaptation to local conditions,and the adopt of low-cost lightweight retaining structure is sum-marized.
