| 摘 要： | 为研究桩心配筋微型桩抗滑特性,进行了滑坡微型桩抗滑特性大型物理模型试验.试验结果可得出,桩心配筋微型桩在加载过程中,各排桩同时受力；滑坡推力对桩心配筋微型桩的影响范围为滑面上下各20倍桩径的范围内；桩心配筋微型桩在抗滑工程中主要是受弯破坏,易破坏点为滑面上下3倍桩径处；微型桩群桩的破坏过程是从迎滑第一排桩开始；微型桩能有效提高滑坡体的稳定系数.

| Abstract: | In order to study the anti-sliding characteristic of micropile with center reinforced,test of arge-scale physical model was conducted.The results show that each row from the group is forced simultaneously;sphere influenced by landslide thrust on the pile was under the range of 20 times the pile diameter.The damage form of micropiles with center reinforcement arrangement was bending failure which occurred 3 times the pile diameter above and below the sliding surface.Destruction process with micropile began with the first row of the group,and landslide with micropiles can get better secure. |
