摘要
基坑工程设计中土体的水平抗力系数与开挖时间、空间、地质条件和加固条件、开挖土体所处的深度、护坡土体的宽度等密切相关 ,是基坑开挖时间、空间、地层土性条件、加固条件、环境条件等的函数。为便于工程应用 ,本文通过现场试验实测资料的整理 ,并结合程序反分析和理论研究 ,提出了一种等效水平抗力系数Kh 来综合反映土体抵抗变形的能力 ,并建立了被动抗力K的实用计算方法。
The lateral resistance factor of soils in excavation is influenced by many factors It should be noted that these factors are the function of the time and location for excavation, and the environment It is difficult to determine the factor of an excavation design An attempt is made on easy to get the factor for engineers A new parameter called the equivalent lateral resistance factor of soils is proposed in the paper The properties of soil and construction procedures can be integrally considered What is more, a practical formula for passive resistant of soil is also presented
