摘要
为研究地基处理中各项影响因素与抗压强度的关系,基于对捷太格特(中国)技术中心建设工程,依据JGJ 79—2002《建筑地基处理技术规范》中深层搅拌法(湿法)进行水泥土搅拌桩室内配合比试验。通过对试验数据整理分析发现,抗压强度随水泥掺量提高而增加、随龄期增长而增大,在不同物理力学性质的地基土,水灰比的选择也会有所不同。建议选择水灰比0.55较合适,更有利于提高地基土的承载力。
In order to study the relationship between various factors and compressive strength in foundation treatment,based on the construction of JTEKT(China) technological center and the middeep mixing method(wet method) of JGJ 79—2002Technical code for building foundation treatment,the cement mixing pile indoor mix proportion test is completed.Through analyzing the test data,it is found that the compressive strength increases with the increase of the cement content and increases with the age,and the selection of water-cement ratio will be different in different physical and mechanical properties.It is suggested that the ratio of water-cement to cement is 0.55,and the bearing capacity of foundation soil can be improved.
