| 摘 要： | 针对连云港地区滨海相软土的工程特性，讨论了采用粉喷桩加固滨海相软土地基的加固效果，包括采用标准贯入试验，取芯无侧限抗压强度值对粉喷桩的桩身质量进行评价以及通过复合地基的静载荷试验评价粉喷桩复合地基，同时根据连云港地区的软土特征建立了标准贯入击数与无侧限抗压强度之间的关系。 |

| Abstract: | In Lianyungang area, there is much marine soft soil which is of low bearing, high compression and high natural water content. Several methods are used to test the improvement effect of DJM (Dry Jet Mixing) for marine soft soil ground. These methods include the standard penetration test (SPT), the unconfined compression test of boring samples, and the static loading test of composite ground.The relationship between SPT blow counts and the strength of unconfined compression is established.The results show that SPT is a good method for testing quality of DJM piles. |
| Keywords: | DJM piles unconfined compression strength soft soil composite ground Lianyungang area Jiangsu province |
