| 摘 要： | 面层是复合土钉支护系统中重要的组成部分,且承受边坡水土压力、土钉拉力等荷载是施工中面层设计的必要环节。在大部分的复合土钉支护工程设计与施工过程中,仅对土钉直径、间距及长度进行设计计算,对支护面层直接按照常规厚度进行采取,对支护的设计方案的工程费用带来不必要的浪费。根据弹性梁理论推导出支护面层的设计方法并通过实例对面层进行了强度验算和设计。

| Abstract: | Topping is the important part of composite soil nail support system,and bears the pressure of side slope water and soil,and the pressure of soil nails,so it s an necessary link in the middle layer design.In most composite soil nail support project design and construction,only the diameter,spacing and length of the soil nail are computed,the support topping directly uses the common thickness,and these can bring unnecessary waste to the engineering cost of support design scheme.In light of the beam on elastic... |
