摘要
在采用FLAC对动载下加筋土挡土墙失稳机理数值模拟分析的基础上 ,提出 10 4国道界河立交桥加筋土挡土墙的加固方案。通过采用多排预应力锚杆、2~ 4次注浆、墙体表面喷钢筋混凝土等措施 ,加筋土挡土墙加固后预应力稳定 ,墙面无变形 ,没有对原功能造成任何不利影响。锚喷网联合加固方案对挡土墙的加固是成功的。
On the basis of the simulative analysis of the failure mechanism under vehicles loading of the reinforced retaining wall in the crossroad of G104 by means of the numerical analog calculation software FLAC There is the stable tress and the transmutativeless surface in reinforced retaining wall after reinforced by the measures of 1~3 line bolting, 2~4 times injection and shotcrete lining on the surface, and there is no effect on the primary functions of the reinforced retaining wall It is successful to reinforce the reinforced retaining wall by use of the shotcrete wire mesh bolting
