摘要
软土地区地基真空预压处理后静力触探经验公式在国内未见报道。经过多年在黄骅港湾地区真空预压处理后地基的静力触探实践,通过11个场地静力触探锥尖阻力qc与地基土真空预压处理后物理力学指标平均值的相关分析研究,得出了一套地基真空预压处理后静力触探经验公式,对沿海软土区划分地层,计算地基承载力、压缩模量、不排水抗剪强度、桩极限侧阻力,预压处理层性质的评价等具有重要参考意义。
The static cone penetration test formula for vacuum preloading foundation in soft soil area has never reported in China,Through years of practice in Huanghua Lough, a set of static cone penetration test formula has been obtained for vacuum preloading foundation in soft soil area by researching on the correlativity among cone point resistance, physico-mechanical indexes in 11 projects, The set of formula has important reference sense to calculate the foundation bearing capacity, modulus of compressibility, undrained shear strength, ultimate side resistance of pile, and to assess the character of vacuum preloading foundation in soft soil area.
