| 摘 要： | 莽山公路k25＋600～k25＋620段需要填筑,本段紧邻县道067,受县道067的影响,不能采用放缓设计边坡时,提出了路堤边坡抗滑桩超前支护的思想。并用midas数值计算软件对填筑体进行了位移分析,对抗滑桩进行了位移及内力分析,得出位移和内力均在安全范围之内,对类似工程的设计有一定的借鉴意义。

| Abstract: | Mangshan highway k25 ＋600 ～ k25 ＋620 section needs filling,it is close to the county road 067,and cannon slow down the side slope because of county road 067.The concept of pre-reinforced by anti-sliding piles in road filling slope is proposed.The Midas numerical calculation is used to study the displacement of filling body and the displacement and internal force of anti-sliding piles.Result display the displacement and internal force are in the safe range,This paper has a certain reference value for similar engineering design. |
