摘　　要：分析了天津中心渔港地区软弱土层的物理力学性质的规律性,简单阐述了真空预压的加固机理。根据现场原位试验及土工试验数据,对比分析了采用真空预压加固前后土体的含水率、孔隙比、压缩系数、压缩模量及原位测试数据。分析结果表明,中心渔港地区真空预压加固效果明显,适应性较好。Abstract： Firstly, the regularity of the physical and mechanical properties of the soft soil in Tianjin central fishing port areas is analyzed here, and the reinforcement mechanism of vacuum preloading is briefly discussed. Then the moisture content, void ratio, compression factor, compression modulus and in-situ test data of the soil before and after the vacuum preloading are compared and analyzed based on situ testing and soil test data. It is concluded that the effectiveness and adaptability of the vacuum preloading technique in Tianjin central fishing port areas are better.
