摘要
提出了浙中1 000 kV变电站新建工程地基分区域按不同能级组合强夯处理设计方案。为检测强夯对填土地基的加固效果,确定强夯后地基的物理力学参数及地基承载力特征值,采用静力载荷法、动力触探、瑞利面波法和土工试验等对强夯处理后的地基进行检测。综合检测结果表明,经强夯处理后地基性能明显改善,地基承载力和变形模量均达到设计要求,强夯处理效果较好,为后续进一步地基处理提供参考依据。
The paper provided a design scheme of dynamic compaction treatment for a new substation project of 1000 kV is put forward according to different energy levels. In order to test the effect of dy-namic compaction on the soil foundation , determine the physical and mechanical parameters of the foundation after dynamic consolidation and the characteristic value of foundation bearing capacity. The static load method, dynamic sounding, rayleigh wave method and geotechnical test of tamping the foundation after treatment were detected. Comprehensive test results show that the performance of ground is improved obviously after dynamic consolidation treatment, both the bearing capacity and the deformation modulus of the foundation have reached the design requirements. The effect of dynamic compaction is better and provides a reference for the further foundation treatment.
