边坡支护方案的技术与经济机理研究

Study on technical and economic mechanism of slope support scheme

边坡的稳定性评价与治理一直是滑坡灾害研究中重要的一环,尤其是涉及到城市中居民小区的边坡安全性尤为重要。从边坡支护方案的遴选、遴选的基本原则、支护与高楼施工的关系、稳定性分析的方法四方面,详细阐述边坡结构稳定性与经济性有机组合的机理,其次阐述排水的方式,并基于景观绿化的原则,归纳得出治理的理念可以分为六个部分:头需轻(减载)、脚要重(增强)、身必固(拉撑中部)、侧须限(侧边距离)、水应防(排水)、景宜美(绿化增强)。从而以点带面构成边坡治理的系统性规律,可推广或借鉴用于其他边坡的治理。

Slope stability evaluation and treatment has always been an important part of landslide disaster research,especially the slope safety of urban residential areas.Through four aspects:selection of slope support design scheme,basic principle of slope scheme selection,relationship between slope reinforcement and high-rise building construction,and method of slope stability analysis,this paper expounds the mechanism of organic combination of slope structural stability and economy,then expounds the way of slope drainage,and then expounds the principle of slope landscape greening.Thus,it is concluded that the concept of slope treatment can be divided into six parts:light head(load reduction),heavy foot(enhancement),solid body(middle part of bracing),side limit(distance from edge),water prevention(drainage)and the landscape should be beautiful(greening enhancement).So as to form a systematic law of slope treatment from point to area,It can be popularized or used for reference in the treatment of other slopes.
