摘要
土的静止侧压力系数K0为土体在无侧向变形条件下水平主应力与竖向主应力之比。目前国内可通过原位测试、室内测试以及经验换算等手段确定K0值。广州市软土的特性,使在地铁工程中K0的取值不能完全依赖经验值,确定K0值在广州市软土地区的地铁工程项目中具有重大的意义。
Static lateral pressure coefficient K0 is the ratio of horizontal principal stress and vertical principal stress under the condition of no lateral deformations for soil. The K0 value can be determined by in situ test, indoor test and conversion. Characteristics of soft soil in Guangzhou City, make the value of K0 is not entirely dependent on experience value in the un-derground engineering to determine the value of K0 is of great significance in Metro Project in soft soil area in Guangzhou ci-t y.
