通过北方某高速公路滑坡治理工程加固的实际案例,从技术角度比较研究了滑坡治理的不同方案。经分析研究主要工程量指标,采用抗滑钢管桩和锚杆联合加固技术进行处理所用的锚杆用量远远小于路基边坡与下部挡土墙分别采用预应力锚杆联合加固的锚杆用量,同时考虑到袖管灌浆、袖管劈裂注浆、抗滑钢管桩等增加的费用,综合认为采用抗滑钢管桩和锚杆联合加固技术是最合适的。
Through the actual case of strengthening a landslide control project in a highway in northern China, different schemes of landslide control are comparatively studied from a technical perspective. After analyzing and researching the main engineering quantity indexes, the amount of anchor used for the treatment with anti-slip steel pipe piles and anchor reinforcement technology is far less than the amount of anchor bolts combined reinforcement by prestressed anchors and the subgrade retaining walls respectively Taking into account the increased costs of sleeve grouting, sleeve splitting grouting and anti-slip steel pipe piles, etc. It is considered that the combination of anti-slip steel pipe piles and anchor rods is the most appropriate.
