本文介绍了加筋土公路路堤的荷载试验情况。该路路堤设计荷载汽—20,路堤竣工后曾按汽—20标准等代土层厚度进行堆荷试验,铺筑路面基层后,又用汽—15和汽—10组合进行汽车载荷试验,先后按桥涵规范规定的荷载横向车道图式及偏心受载图式进行测试。试验表明无论堆荷或汽车荷载,墙面最大相对位移大体为0.0005H(H为墙高)随载荷时间的延长,位移并不增大,且有减小或恢复趋势,具有刚柔结构的特征。
This paper introduces the load test of reinforced earth embankment. The road embankment design load steam -20, after the completion of the embankment has been based on steam -20 standard thickness of the pile for pile load test, after paving the pavement base, but also with steam -15 and steam -10 combination of vehicle load test, successively According to the norms of the bridge and culvert load horizontal lane pattern and eccentric load diagram for testing. The test shows that the maximum relative displacement of the wall is about 0.0005H (H is the wall height) regardless of the pile load or the vehicle load. The displacement does not increase with the trend of decreasing or recovering and has the feature of rigid-flexible structure .
