摘要
公路边坡的稳定性及变形分析是公路工程研究的重点,更是保护用路人生命财产安全免受滑坡侵害的关键。文章依托沈阳(王家沟)至铁岭(杏山)段高速公路籍家岭边坡研究案例,通过定性分析与模拟计算相结合的方法对该边坡的稳定性进行分析评价并提出支护建议。综合考虑处理原则与处理方式,认为对于滑塌段落的局部处理宜采用回填+浆砌防护;对于已发生变形位置,宜采用锚杆框架+浆砌片石护面防护;对于K819+440~K819+620段落,宜采用锚杆框架+浆砌片石护面防护。
The stability and deformation analysis of highway slope is the focus of highway engineering research,and it is the key to protect the safety of road users'lives and property from landslides.Based on the research case of the Jijialing slope of the Shenyang(Wangjiagou)-Tieling(Xingshan)section of the expressway,the slope stability is analyzed and evaluated by combining the qualitative analysis and simulation calculation,and the support suggestions are put forward.Considering the treatment principles and treatment methods comprehensively,it is considered that backfill+mortar protection should be used for the local treatment of the collapse section.For the position where deformation has occurred,it is advisable to use bolt frame+mortar flagstone protection.For K819+440~K819+620 section,it is advisable to use bolt frame+mortar flagstone protection.
