粉喷桩处理液化地基的作用机理、设计要点和检测方法

The action mechanism, design, and detection method of the CDJM pile applied to the liquefaction ground treatment

对粉喷桩处理液化地基的作用机理、设计要点和检测方法进行了论述。结合工程实例说明了粉喷桩是处理液化地基的一种切实可行的措施，而剪切波速法是粉喷桩处理液化地基效果的有效检测方法。

The paper expounds the action mechanism, design gist and detection method of the liquefaction ground treatment using the cement dust jet mixing(CDJM) pile. An engineering exam- p1e shows that CDJM pi1e is a good means of the liquefaction ground treatment. and the shear wave velocity measurement is an effective method to detect effect of the liquefaction ground treatment.
