采用自行设计、改进的固结仪进行了低路堤情况下交通荷载的模拟,并总结出不同循环荷载比时路基沉降规律的曲线。在此基础上,进一步推导了循环次数和累积应变的关系表达式。对交通荷载作用下低路堤路基的沉降进行了初步的研究,通过一个工程实例的计算,证明了该方法的正确性,对低路堤设计特别是粤东地区的低路堤设计将有一定的指导意义。
The self-designed and improved consolidation instrument was used to simulate the traffic load under the condition of low embankment and the curves of subsidence under different cyclic load ratios were summarized. On this basis, further deduced the relationship between the number of cycles and cumulative strain expression. The settlement of low embankment subgrade under traffic load is studied. Through an engineering example, the correctness of the method is proved, which will be of guiding significance to the design of low embankment in low embankment, especially in eastern Guangdong Province .
