增北路顺层岩质边坡位于北京市门头沟采空棚户区石泉砖厂地块，主要由强风化砂岩和中风化砂岩组成，因坡脚场地平整诱发滑塌，坡顶局部已建路肩挡墙已出现裂缝，为确保坡脚建筑空间须进一步清坡设挡墙。综合工程特点，通过方案比选，采用逆序施工，从上到下3级支护，第I级采用格构锚拉挡墙永久支护，第II，III级采用钢筋混凝土立柱挡墙支护，安全、美观，并取得了良好的社会经济效益，对类似岩质边坡治理具有借鉴意义。

Zengbei road consequent rock slope located in Shiquan brickworks of mined shanty-towns of Mentougou District,Beijing,is composed of strongly weathered sandstone and weathered sandstone. The slope occurred consequent bedding rock slope while the slope toe grading;and as a result,the rubble retaining wall of the road cracked. However,the rock mass of the slope toe must be cleaned up for more architectural space;so, the permanent slope was built as well. The rock slope was treated with lattice anchor retaining wall and cast-in-site column type retaining wall according to the characters of the slope by scheme comparison and top-down construction method. The step I was lattice anchor retaining wall;while the steps II and III were cast-in-site column type retaining walls. The bracing system is safe and beautiful,which achieves good socioeconomic benefits. It has reference value for the similar projects.
