在凯科发展研究院多年前率先提出并倡导的采用化学-物理复合法来加快淤泥等软土的固结速度和大幅度提高其固化效果的基础上，联合中交四航工程研究院最新的真空预压技术，以珠江三角洲淤泥为例对化学处理后的高含水率淤泥进行室内三维真空预压排水模型试验，并同步进行常规的真空预压试验。试验结果表明，用真空预压法来辅助化学加固后的淤泥，在沉降速率上明显大于常规真空预压的速率；在相同的固结时间内，复合法所取得的无侧限抗压强度均远远高于单一真空预压法所取得的强度；同时在用新加坡海洋淤泥进行的相关同步试验中，复合法所取得的数倍高的抗剪强度也进一步验证该方法的有效性及优越性。因此，这个化学-物理复合法对于加固淤泥等软土地基，无论在学术上还是在大面积填海造地工程实践中均有广阔的发展和应用空间。

Based on the chemical-physical combined method(CPCM) to more efficiently increase consolidation effects of soft clay or clay slurry and incorporated with the advanced vacuum preloading(VP) technique with vertical drains,new lab testing results of three-dimensional consolidation on the chemically treated Pearl Rivel marine clay under VP were presented;while parallel tests with pure marine clay under VP were conducted. The testing results show that the consolidation rate of the models using CPCM is obviously faster than that using conventional VP method. Within the same consolidation time,the compressive strength of the consolidated soil achieved by CPCM is much higher than that achieved only by applying VP. Furthermore,the similar tests conducted on Singapore marine clay also supported the findings that CPCM has super effectiveness and advantages. This totally new CPCM has therefore high development potentials for both academic research and engineering application especially in land reclamation.
