摘要
为了研究工程实际中锚杆-抗滑桩等多种加固手段的效果,该文采用有限元分析软件MIDAS-Gts对贵广高速铁路DK703+626.510路段左侧边坡进行稳定性分析,并采用锚杆、锚索+抗滑桩联合支护的支护形式对边坡进行处理,结果表明:锚杆、锚索-抗滑桩联合加固能够有效减少边坡滑移,边坡的总位移、水平位移分别降低37%和67.2%,但由于支护结构施工,同时也将产生更大的沉降。抗滑桩应力最大值为785kPa,位于抗滑桩地面以下约3/4处,抗滑桩的受力分布情况大致相同,均呈“中间大、上下小”的分布模式,且桩右侧远大于桩左侧。
In order to study the effects of various reinforcement methods such as bolts-anti-slide piles in engineering practice,this paper used the finite element analysis software MIDAS-Gts to analyze the stability of the left side slope of the DK703+626.510 road section of the Guizhou-Guangzhou high-speed railway,and adopted the joint support mode of bolts,anchor cable+anti-slide piles to treat with the slope.The results showed that the joint reinforcement of anchor rods,anchor cables-anti-slide piles can effectively reduce slope slippage,and the total displacement and the horizontal displacement of the slope are reduced by 37%and 67.2%respectively,but due to the construction of the supporting structure,greater settlement will also be generated.The maximum stress of the anti-slide pile is 785kPa,which is located about 3/4 of the anti-slide pile underneath the ground.The force distribution of the anti-slide piles is roughly the same,with the shared distribution pattern of"large in the middle and small in the top and bottom",and the right side of the pile has a much larger force than the left side.
