| 摘 要： | 通过某码头工程典型试验区进行的强夯试验，研究了在单点夯试验过程中夯沉量与夯击次数的关系、地基土水平位移和深度的关系、夯击次数与孔隙水压力的关系及孔隙水压力增长与消散和时间的关系；在试验块强夯后，进行了静载试验、静力触探试验和钻孔取土室内土工试验。通过对强夯前后进行对比，得到了强夯法加固吹填砂地基的效果，提出了合理的强夯施工参数和控制工艺，并得出了一些有益的结论。

EXPERIMENT STUDY ON BACKFILL SAND FOUNDATION BY DYNAMIC COMPACTION |
| |
| Abstract: | Dynamic compaction is a better way for the treatment of sand filling foundation in the Yangtse River region.This paper has discussed the consolidation test of sand filling foundation in typical area of a port project and investigated in single rammed point testing the relation curve of ramming number and settlement, the relation between horizontal displacement and depth of soil,the relation curve of ramming number and pore water pressure,and the relation curve of pore water pressure and time.The loading test, static cone penetration test and soil laboratory test have been done after the dynamic consolidation in the area. According to the conclusion before and after the testing, some appropriate engineering parameters are obtained and some advices are put forward. |
