地基处理及强夯施工质量控制

Detailed Quality-controlling Measure of Dealing the Foundation and the Dynamic Compaction

采用强夯施工法,对大面积回填土建筑场地地基处理,具有加固效果显著,适用土类广、设备简单、施工方便、节省材料、施工周期短、施工文明和施工费用低等特点,而且强夯处理后的地基承载力及沉降量,均能满足基础结构设计要求。以±200kV舟山多端柔性直流洋山换流站站区内强夯施工为例,介绍了工程概况、现场地质状况、强夯压实处理方案、工程质量监控等技术措施及地基处理经验。

Adopting the dynamic compaction to deal the foundation of the buildings which fills the big area with soil has much characteristics such as big reinforcing-effect,being applicable to all kinds of soil,briefness of the equipments,convenience of the construction,saving the materials,short period,civilization of the construction and low expense etc. Furthermore, the empress and sinking-quantity of the soil which is dealt with strong popular method can satisfy the design of the foundation structure. This text takes the dynamic compaction method in the Multiterminal HVDC project of ±200 kV ZhouShan convertor station as an example to introducing the general situation,the field geological condition,the project of the dynamic compaction,the technical measure of controlling the engineering quality and the experience of dealing the foundation.
