交通荷载下低路堤高速公路路面路基振动测试与分析

Vibration Measurement and Analysis of low embankment freeway pavement and roadbed Under Traffic Loadings

交通荷载的作用使得路面路基产生动力响应,为了掌握和分析交通荷载在低路堤高速公路路面路基中的振动响应,对连盐高速公路一低路堤工程段进行了现场测试,采用强震仪及动土压力盒测试在不同车型、不同车速工况下路面及路基不同深度的动力响应,根据对测试结果的分析,得出了一些有价值的结论,对今后指导低路堤高速公路路基设计和处理有一定的意义。

The traffic loading make pavement and roadbed produce dynamic response. For mastering and analyzing vibration response of low embankment freeway pavement and roadbed under Traffic Loadings, the thesis have spot measurement on a low embankment engineering segment of LianYunGang- YanChen Freeway, testing dynamic response of pavement and different depth roadbed under different vehicle and velocity using strong shock apparatus and dynamic earth pressure cell. According to the analysis about testing result, some value conclusions were obtained, Therefore it has certain significant for conducting roadbed design and dispose of low embankment freeway aftertime.
