摘　　要：静力触探法检测水泥搅拌桩是一种常用的检测方法,文中依据水泥搅拌桩的预置管法静力触探损伤机理,以实际工程参数为例建立数值模型,研究贯入过程中影响损伤区范围的主要因素,并对静力触探模拟结果进行了详细分析,通过研究可以更精确地反映水泥搅拌桩的强度,对工程实际应用具有参考意义。Static penetration detection is a common method to detect cement mixing pile. In this paper, according to the damage mechanism of static penetration of cement mixing pile with preset pipe method,a numerical model is established by taking actual engineering parameters as an example, and the main factors affecting the damage area during penetration are studied, and the simulation results of static penetration are analyzed in detail. The research can reflect the strength of cement mixing pile more accurately, which has reference significance for engineering practical application.
