摘要
多道瞬态面波法对强夯地基进行大面积普查,既能降低成本、扩大检测面,又能提高检测速度和精度。本文总结了多道瞬态面波法在地基处理检测的定性和定量评价中取得的成果,介绍了该方法在广西、辽宁两个国家重点工程项目中的应用,并通过强夯前后瑞雷波检测结果与静载试验等的对比分析,得到了应用多道瞬态面波法在沿海地区开山填海碎石土地基的相关结论等,所得结论可指导多道瞬态面波法在复合地基中的检测工作。
The Multi-channel transicent vibration Rayleigh Wave method is applied to test the Dynamic Compaction, not only decrease cost and spread testing area but also improve testing rate and precision. The text sum up effect in the Ground treatment using Multi-channel transicent vibration Rayleigh wave about determine the nature and fix quantify, and introduce the application in two national importance engineering in Guangxi and Liaoning province. Through the contrast of Rayleigh wave and static load test before and after the treatment of dynamic compaction, we gain some resolutions of multi-channel Rayleigh test about gravel and soil subgrate alongshore area. The resolutions can be used to guideline the Multi-channel transicent vibration Rayleigh testing work application in compound ground.
