To overcome the shortcomings of present divisible e-cash scheme, for the first time, the thesis introduces group signature into divisible e-cash system and view the e-cash withdrawn by users as the group certificate issued by group administrator. As all of ancestor nodes of the payment node arc blindly transformed, the divided parts from one e-cash are no longer linkable.

针对现有可分电子现金方案存在的诸多缺陷，本文首次将适合于大群的群签名思想引人到可分电子现金中，将用户提取电子现金视为群管理员颁发给用户的群证书，通过将支付节点前的祖先节点进行盲化使得同一电子现金分割后的不同分割单元间不再有可链接性。

This paper analyze the stability of soil-nail wall with limit balanced analytical method, and assume the slip surface, destroy surface as dual fold line, circular arc line, parabolic curve or log spiral curve etc.

本文采用极限平衡分析方法对土钉墙内部稳定性进行了分析，滑动面、破坏面的形状假定为双折线、圆弧线、抛物线或对数螺旋曲线进行了描述。

It is assumed that potential sliding surface of the soil in the back of the retaining wall is composed of logarithmic spiral arc and line.

假定挡土墙后土体潜在滑裂面由对数螺线滑动面和平面组合而成，根据挡土墙后土体薄层单元的平衡条件推导出粘性土层主动土压力的计算公式。
