某电厂原始地形为低山及山间平原,该电厂三期场地位于平原地带农田区,主厂房区域部分辅机基础下分布的淤泥层及淤泥质粘土层,设计要求整个淤泥质土层加固后地基承载力特征值≥130k Pa,复合地基压缩模量Es≥15MPa。在考虑对软土地基的加固效果和明显的经济效果的前提下,对该部分场地采用水泥搅拌桩进行地基处理。 The original terrain of a power plant is low mountain and mountain plain. The third phase of the power plant is located in the farmland area in the plain area. The silt layer and the silt clay layer distributed under the auxiliaries of the main plant area are designed to require the entire silty soil layer to be reinforced Foundation bearing capacity eigenvalues ​​≥ 130k Pa, composite foundation compression modulus Es ≥ 15MPa. On the premise of considering the reinforcement effect and obvious economic effect on the soft soil foundation, the foundation treatment of this part of the site is carried out by using the cement mixing pile.
