| 摘 要： | 文章简要介绍了轻型井点结合塑料排水板复合加固法的施工工艺、使用工况。通过靖江新港作业区公用码头段案例,分析了该加固方法的加固效果。分层沉降结果表明该加固方法影响深度约为10 m且在4.0～6.0 m深度范围内的加固效果特别明显;固结计算结果表明,加固后地基承载力为256.3 kPa,8～10m深度处的粉砂夹粉土层的标贯击数由加固前的3击增长到5击,地基承载力提高明显,加固深度达到设计要求。室内土工试验结果表明加固后物理参数各项指标均有所提高。 |

| Abstract: | In this paper,construction technology and application scope of the composite method of well point dewatering and plastic drainage plate were introduced.Based on the engineering of Xingang public wharf in Jinjiang,the reinforcement effect was analyzed.The results of layered settlement indicate that the influencing interval is about 10 m and the reinforcement effect at the depth from 4.0 m to 6.0 m is obvious.The results of calculated consolidation indicate that the bearing capacity is 256.3 kPa before reinforcement.The stroke of silt layer(from 8 m to 10 m in depth)increases from 3 to 5,which shows that the bearing capacity is improved.The parameters obtained from laboratory tests are also improved. |
| Keywords: | plastic drainage plate dynamic compaction layered settlement calculated consolidation laboratory test |
