斜壁 [xié bì]
skew wall
- 研究表明急斜放顶煤开采围岩结构虽然与缓斜煤层长壁放顶煤不同，基本顶（老顶）和直接顶只是在工作面的一侧，但仍然不能忽视它对工作面矿山压力显现的影响。
The result of research reveals that strata behavior of basic roof and immediate roof on working face can not be neglected in mining steep seams. - 以某巴拿马型营运散货船为研究对象,分析该船货舱区域横舱壁结构损坏的根源是设计结构计算应力超过许用值,通过细化有限元分析计算,对重压载舱横舱壁区域提出中间槽条加深方案,在槽形舱壁斜板同一平面的下墩结构内设置附加肘板,以降低因结构突变而产生的应力集中问题。
The cause of construction damage of the bulkhead structure for the 73 000 t panama-max bulk carriers analyzed by CCS′s Rules and Regulations and direct calculation method is that the local working stresses are large than the allowable ones.A resolve plan is proposed of strengthening the corrugated bulkhead,as well as putting up the additional brackets in the lower stool right under the slope plates of the bulkhead in order to reduce the problem of stress concentration due to structural discontinuity. - 文摘:介绍了查庄煤矿在31005工作面使用倾斜长壁仰斜开采的情况及技术管理措施，对相似条件下此类采煤法的使用提供了可借鉴的经验。
Abstract: The case of inclined longwall and overhead mining at 31005 face in Zao zhuang Coal Mine and techni;cal manage measures are introduced.It also provides some reference experiences for using the mining methods under similar conditions.
