| 摘 要： | 深圳国际会议展览中心地基淤泥层厚度达4 m，设计中采用塑料排水板加堆载预压方法对其进行排水固结。根据沉降和孔隙水压力观测结果，该地基平均沉降达淤泥厚度的21.2%，剩余沉降小于100 mm，固结度大于90%。处理后的地基十字板强度增加了3倍，静力触探锥尖阻力增长了5倍，回弹模量满足设计要求。

| Abstract: | The depth of the silt layer in foundation of Shenzhen International Conference and Exhibition Centre reaches 4 m.The design adopted plastic drainage board method and preload compaction method to consolidate the soft foundation.Based on observed data of settlement and pore pressure,the average settlement value reached 21.2% of silt depth, the residual settlement was less than 100 mm, and the degree of induration was more than 90%. The strength of vane of silt after treatment increase by 3 times and the static point resistance by 5 times.So, its lasting elastic modulus can meet the design requirements. |
