摘 要: | 垫层对复合地基承载力的提高作用已成共识,但建筑地基处理技术规范中并没有考虑这一影响。针对这一问题,本文通过对加垫层和不加垫层两种单桩复合地基承载力的载荷比较试验,对垫层的作用机理进行了分析,并建议了相应的承载力特征值计算公式。

Study on the characteristic load bearing capacity of Jet-Mixing Cement-Soil pile composite foundation |
| |
Abstract: | Although the function of load bearing capacity improvement by cushion under composite foundation has been acknowledged for a long time, no attention is paid in the relative national code. The in situ comparing load tests are carried out on two groups: one with cushion and the other without. Then the mechanism of cushion working is analyzed, and the corresponding characteristic load bearing capacity calculation formula is suggested. |
