拱面墙

Considering the effect of the angle of internal friction on the inclination of sliding plane of soils behind retaining wall, circular and catenary, the two shapes of minor principal stress arch are theoretically analyzed. According to the shapes of minor principal stress arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are gained.

为克服现有考虑土拱效应的土压力计算方法不能考虑墙土摩擦角变化对挡土墙后土体滑裂面的影响的不足，考虑墙土摩擦角变化对挡土墙后上体滑裂面倾角的影响，对圆弧和悬链线两种拱形分别进行了分析，并与现有方法计算结果进行了比较。

Then the failure mode and the coefficient of stability of the displaceable blocks were studied respectively.

主要内容包括：①在野外地质调查基础上，通过统计分析得到地下厂区结构面的优势方位；对结构面工程地质特性进行了分析；根据结构面的空间组合关系，搜索出可能在主厂房洞室的顶拱和边墙部位出露的块体，并分析了各块体的可能滑移方式及其稳定性系数。

And the main contents of this dissertation are:(1)The engineering geological features of discontinuities in surrounding rock mass were analyzed on the basis of field geological survey and the preferred orientation of the main discontinuities were derived. Then the displaceable blocks distributing on the roof and sidewalls of main chamber were searched out taking the intersecting relationship of discontinuities into consideration. Then the failure mode and the coefficient of stability of the displaceable blocks were studied respectively.

The instability ways of block were fall at vault and single or double side glide at nance and sidewall

块体可能的失稳方式主要为拱顶直接掉落、拱腰和边墙部位出现单滑面或双滑面滑动块体。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
