基于多源数据的红土砾料结构承载性能评价

为准确评估红土砾料结构层的路用性能，以赤道几内亚三个路段的红土砾料底基层为研究对象，采用现场承载板试验、PFWD动态回弹模量测试和贝克曼梁测试进行综合评价。结果表明:红土砾料的结构承载性能较好，影响因素有板结、湿度、荷载作用次数等，动态回弹模量与承载板模量、CBR值具有较好的相关性。

Evaluation on Structural Bearing Capacity of Laterite Gravel Based on Multi-source Data

In order to accurately evaluate the road performance of the structural layer of laterite gravel, taking the subbase of laterite gravel in three sections of Equatorial Guinea as an example, the structural bearing capacity has been comprehensively evaluated by the field bearing plate test, PFWD dynamic resilient modulus test and Beckman beam test. The results suggest that the structural bearing capacity of the laterite gravel is better, which is affected by hardening, humidity and the number of loading. The dynamic resilient modulus has a good correlation with the modulus of bearing plate and CBR value.
