| 摘 要： | 分析了土体的原位应力状态及影响土的侧压力系数K0的因素,探讨了K0与φ′、K0与μ、K0与OCR等参数之间的内在联系,建议了一种与P-S曲线相关联的K0计算方法,这种方法不仅理论上较为完善,而且为工程人员提供了设计依据,是一种很实用的方法。

| Abstract: | This paper analyzes the stress state of subgrade in site, and the factors of influcing the coefficient K 0 are discussed . Moreover,some approaching methods,which can be used to calculate the coefficient K 0are introduced , A calculating method,which is internected with the P-S curve is proposed. This method is not only perfect in theory, but alse it is a very practical method which can be used to guide the engineers to design. |
