地基改良加固效果检测
test of effect of foundation improvement and stabilization

di!1 gailiangJ旧gu xiaogUO Jianee地基改良加固效果检测(test of effeet offoundation imProvement and stabilization) 利用地球物理参数评价地基土改良加固后性状的工程地球物理勘探方法。地基土改良加固后是否达到预期的设计指标，有多种检测方法(载荷试验、触探、标准贯入试验等)，物探检测方法是其中之一。它的优点是成本低、效率高。最常用的物探检测方法是波速测试。岩土的弹性波速度，取决于岩土的密度、结构和物理力学性质。因此，分别测试地基土改良加固前后的弹性波速度，即可评价地基土改良加固的效果。工程上常用的检测方法是波速测试中的单孔法、跨孔法和瑞雷波法。三者任择其一，在地基土改良加固前后，分别测定纵波、横波或瑞雷波速度。用实测的弹性波速度值，或用波速与地基土承载力和压缩模量等强度指标建立的相关关系，以评价地基改良加固的效果。 (韩伯文张静芳)
