格构锚杆组合加固技术在高边坡治理中的应用

以贵州省思南县宏达山水家园工程拟建场地内的高边坡为例,针对该边坡的工程地质、水文地质、岩体结构特征及变形破坏迹象,通过边坡中层面和节理面的空间组合关系确定了边坡潜在滑动面,并以此建立了边坡推力计算模型.在此基础上,通过边坡稳定性评价计算结果确定了该边坡的典型计算剖面,并以此作为边坡设计计算模型.在治理设计过程中采用格构锚杆组合加固技术,系统阐述了其基本设计思路、设计计算过程,并编写了相应的计算程序.工程实践表明,该组合加固技术既能加固深层岩体,又能浅层护坡,同时还能美化环境,具有一定的工程实用价值.

Application of Lattice Rockbolt Combination Reinforcement Technology to Harnessing High Slope

Taking the high slope at a planning construction site,the Hongda Scenery Homeland,located in Sinan County of Guizhou Province for example,and in light of its engineering geology,hydrogeology,rock structure characteristic and deformation and failure indications,according to spatial combination relations between joint surface and layer surface,the potential sliding surface of slope is determined so as to establish the model about thrust force computation of the slope.And then,according to the calculated results of evaluating slope stability to determine the typical computation section of the slope so as to establish design calculation model of the slope.In the design process,the lattice rockbolt combination reinforcement technology is adopted.This paper describes its design idea and design calculation process,and the corresponding computational procedure is compiled.Project practice shows that the combination reinforcement technology can not only reinforce deep rock and shallow slope,but also can beautify the environment;and it has some practical value.
