大高差高角度边坡支护设计

Support design of large height difference and high angle slope

针对大落差高角度边坡进行了支护设计：根据设计规范和相关设计经验,经过勘查、分析,根据边坡坡率和地质条件,垂直高度44.0m范围边坡分两部分进行加固,提出了与之相对应的两种加固方案,主要包括不同支护框架结构和支护参数设计支护设计,筹建方选择了方案1,即高度0～20.0m范围边坡采用锚杆框架结构和锚索框架结构进行支护,高度20.0～44.0m范围边坡采用锚杆框架结构进行维护,同时进行了排水设计.

Aiming at the support design of the big drop and high angle slope ：according to the design specification and related design experience,after investigation and analysis, according to the ratio of slope and the geological conditions, the vertical height of 44.0m range slope is divided into two parts to reinforce, and two corresponding reinforcement scheme is put forward, including different supporting frame structure and support parameters design support design.The construction party have chosen scheme 1, slope which is 0-20.0m high is adopted to use anchor structure and anchor cable frame structure to support, slope which is 0 - 44.0m high is maintained with anchor frame structure,and drainage design was also carried out.
