摘要
瞬态瑞利波测试技术检测公路粉喷桩复合地基加固质量,主要是通过瑞利波波速的变化区分地下不同土层的界面,推算公路粉喷桩加固的有效深度,并根据现场所测波速,建立波速与地基承载力之间的相关关系,对复合地基的强度及加固效果作出综合评价。
The method to check the quality of composite ground made of powder-injection piles, by using transient Rayleigh wave techniques, has been introduced in this paper. By changing Rayleigh wave's velocity, one can differentiate the interface of the ground and calculate the effect depth reinforced by powder-injection pile. Based on the velocity test in the locale, the correlativity between the velocity and the beating capacity of the ground is derived. Therefore, the integrative evaluation for the intension and effect of the composite ground can be worked out.
