瑞利波测试路基回弹模量的试验研究
|
摘要
如何合理、有效、可靠、简便、快捷地对路基施工质量进行实时地检控及工后最终质量的检测评价,一直是交通工程领域比较关心的热点问题。鉴于此,对某高速公路路基针对性地进行了多种测试,其方法包括无损浅层面波测试、弯沉测试、载荷板测试、加州承载比(CBR)测试。根据多种测试方法的现场实测资料,对比分析路基力学性能测试中瑞利波测试、弯沉测试与载荷板试验。运用统计方法原理,得出瑞利波速与回弹模量的经验关系,验证弯沉试验推算土基回弹模量的有效性,并对路基力学性能测试与评价提出建议。
It is always a hotspot problem in transportation engineering field that how to reasonably efficaciously reliably and simply detect and control in real time subgrade construction quality as well as to test and evaluate final quality after construction.The authors carry out pertinently several testing methods toward some highway subgrade including nondestructive low-layer panel wave test,bending test,loading plate test,CBR test.According to on-the-spot factual measurement datum of several testing methods,comparison analysis is made of the Rayleigh Wave test,bending test,on-the-spot CBR and loading plate test in the subgrade mechanical performance test.Using statistical method principle,it gets the experiential relation of Rayleigh Wave velocity and modulus of resilience,and verifies the validity of ratiocinating subgrade modulus
