自从 2 0世纪 80年代以来 ,粉喷桩在软土地基处理中得到了广泛的应用 .加固体的质量和强度是评价粉喷桩加固效果的主要参数 .本文提出了标准贯入试验检测方法 ,并给出了粉喷桩的测试结果 ,研究表明标准贯入试验是一种简单而有效的粉喷桩检测和评价方法 .得到了沿桩长方向的强度特性及标准贯入试验击数和无侧限抗压强度之间有着良好的对应关系 Since the 1980s, the DJM pile has been widely used in the soft soil foundation treatment.The quality and strength of the reinforcement body is the main parameter to evaluate the reinforcement effect of the DJM pile.This paper presents the standard penetration testing method, The test results of DJM are given, and the results show that the standard penetration test is a simple and effective method to detect and evaluate DJM. The strength characteristics along the length of the pile and the number of standard penetration tests Lateral compressive strength has a good correspondence between
