摘　　要：浆固碎石桩是一种新型桩基类型,文中探究了该桩基优化后的变形特性,通过控制变量法对该材料制成的试块进行尺寸和强度测试。结果表明,试块线性膨胀率随养护龄期变大而先增大后变小再增大,膨胀剂掺量与线性膨胀率成正比;试块线性膨胀率随养护龄期增大而先增大后减小再增大,水胶比则与线性膨胀率呈先减小后增大的变化趋势;模具对试块强度影响较小,少量膨胀剂对试块的强度影响不大;试块强度与水胶比的关系受到膨胀剂掺量影响。The slurry solid gravel pile is a new type of pile foundation material.Now,the deformation characteristics of the material are explored,and the size and strength of the test block made of the material are tested by the control variable method.The results show that the linear expansion rate of the test block increases and then increases with the curing age is proportional to the linear expansion rate;the linear expansion rate increases with the curing age;the relationship between the test block strength and the water gel ratio is affected by the amount of the expansion agent.
