滑坡治理中格构式锚杆框架结构设计

Design of lattice frame anchor structure for landslide control

结合略阳县城狮子山滑坡的治理,讨论了格构式锚杆框架结构治理松散堆积体滑坡设计的全过程。根据防治区的工程地质情况和相应的规范要求,确定了防治工程的安全等级。利用格构式锚杆框架结构所采用的小间距、小吨位锚杆及连续格构梁柱,从而使格构梁柱受力较均匀,适合松散堆积体滑坡治理的需要,即同时满足深层抗滑和浅层护坡。给出了坡面推力的计算模型和计算公式,对于格构式锚杆框架结构中的格构梁柱、锚杆和框架间面板也分别给出了相应的结构设计方法和公式,再就施工中应注意的事项给出了明确的建议和要求。

Taking shizishan landslide control in Lueyang Country as an example, the whole design process of lattice frame anchor structure are studied. Firstly, according to the geological conditions and technical code for design, safety criterion for landslide control is confirmed. Secondly, by making use of the features of lattice frame anchor structure which can protect slope and retain stability of landslide together with its small space between beams and light anchor, the calculation model and formulas of slope force are dealt with and the design process of lattice beam and pillar as well as anchor and plate are introduced carefully. Finally, the advice and request for construction are specific ally put forward.
