EXPERIMENTAL STUDY ON STIFFENED DCM PILE IN LABORATORY
-
摘要: 水泥土组合桩是由水泥土和芯桩组成的组合桩型 ,二者的共同工作对水泥土组合桩的承载性状有重要影响。通过对混凝土芯桩与水泥土组合试件的静载荷试验 ,研究了水泥土强度及其他因素对芯桩与水泥土界面摩阻力的影响 ,为水泥土组合桩的设计施工提供了可靠依据。Abstract: A stiffened DCM pile consists of soil-cement and core pile, whose cooperation has an important influence on the bearing behavior of the stiffened DCM pile. The effects of soil-cement strength and other factors on the friction resistance are researched by static loading tests of concrete core piles and soil-cement specimens, which provided a reliable basis for the design and construction of soil-cement composite piles.
