锚杆格构梁+土钉植草+钢管桩挡墙的组合支护方法在某半岩半土高边坡加固中的应用研究

Study on the Application of Anchor Lattice Beam + Soil Nailing + Grass + Steel Pipe Pile Retaining Wall Combined Supporting Method to the Reinforcement of Semi-rock and Semi-soil High Slope

广州某地产项目中部分高层建筑物拟建于山坡坡脚处,涉及大量边坡削坡、出土、加固工程。根据场地半岩半土高边坡的工程地质特征,结合高层建筑的布置要求,在治理设计过程中采用了锚杆格构梁+土钉植草+钢管桩挡墙的组合支护加固技术。实践证明,此种加固方法在半岩半土质高边坡支护工程中是可行的,取得了良好的应用效果。

Some buildings of a project in Guangzhou will be built in the slope toe, involving a large number of cut slope, excavation, reinforcement engineering. According to the engineering geological characteristics of high slope of semi-rock and semi-soil, and the layout requirements of the high-rise building in the design process, combined support reinforcement technology is used, which are composed of anchor lattice beam, soil nailing, and steel pipe pile retaining wall combined bolting reinforcement technology. Practice has proved that the reinforcement method is feasible in the semi-rock and semi-soil high slope supporting project, and achieved good results.
