粉喷桩固化剂新型材料试验与分析

THE TESTING STUDY FOR NEW MATERIAL OF SOLIDIFICATION IN DJM PILE

介绍一种新型材料与水泥的混合物作为粉喷桩固化剂的混合料加固土,讨论了加固土的无侧限抗压强度、抗拉强度和变形模量的试验结果和它们之间的相互关系以及影响加固土强度的主要因素。

The mixture of slag and cement used as solidification of DJM pile is studied, and also unconfined compression strength, split tensile strength and modulus of deformation of the mixture are analyzed. Then several main factors affecting unconfined compression strength of specimen are discussed, and general law for prediction of unconfined compression strength is obtained. In addition, the main regression relationship for split tensile and compression strength, deformation modulus and unconfined compression strength are investigated.
