我国土地资源紧缺,珍惜土地资源、合理利用土地和切实保护耕地是我国的基本国策。文章采用电阻式土压力盒,DH-3817动静态应变测试系统,较好地实现了车辆行驶荷载作用下路堤不同层位的连续应力测试,探讨了低路堤条件下车辆轴重、路面平整度、车辆行驶速度、对交通荷载引起的附加应力分布的影响,并得出了交通荷载引起的附加应力的分布范围及其影响深度,为低路堤条件下采用浅层固化技术进行软土处置提供了依据。
The shortage of land resources in our country, treasuring the land resources, using the land rationally and effectively protecting the cultivated land are our country’s basic state policies. In this paper, the resistive earth pressure box and DH-3817 dynamic and static strain testing system are used to test the continuous stress of different layers of the embankment under the driving load. The axle load, surface roughness, The influence of traffic speed on the distribution of additional stress caused by traffic load and the distribution range of the additional stress caused by traffic load as well as the depth of influence were obtained, which provided the basis for the soft soil disposal by shallow curing technology under the condition of low embankment .
