| 4. | Through analyzing those calculations , it gets some significant conclusions about the potential failure surface of the steep reinforced slopes
通过对计算结果分析，论证了关于加筋陡坡潜在破裂面的有意义的结论。 |
| 5. | In underground engineering , the cavity axis should be designed to intersect fractures with large - angle ( 90 ) as it traverses fault and joints
摘要在地下工程中，当洞室穿越断层、节理等破碎带时，应尽可能使洞轴线走向与破裂面的走向呈大角度相交( 90 ) 。 |
| 6. | There is short of specific and simple calculating method to obtain the cavity axis ' orientation , especially for the rocks with many fractures
然而如何设计洞室轴线走向与破裂面走向大角度相交，一直缺乏具体而简易的计算方法，尤其在破裂面较多且产状明显不同时，这个问题更为突出。 |
| 7. | Because the upper rocks are influenced after the mining lower coal , they glide along the primary bursting surface , and the upper rock layers can form surface - contact fabric by its shear and bulge function
作者认为，下煤层开采后上覆顶板岩层受到二次扰动，其破坏移动主要是沿原有破裂面滑移，由于剪胀的作用，上覆岩层能够形成面接触的覆岩基本结构特征。 |
| 8. | Abstract : based on soil plasticity and limit analysis theory , the second failure surface of backfill behind retaining wall with gentle back surface are studied from two view points of maximum active soil pressure and minimum resistive overturning safety factor , and it is further considered that the minimum resistive overturning safety factor is the best approach to studying the failure mechanism of backfill under complex back surface conditions of retaining structures
文摘:基于土的塑性极限分析理论，从挡土墙最小抗倾覆安全系数和挡土墙背上的最大主动土压力两个角度，分别研究了坦墙后土体中第二破裂面的位置，认为在复杂的挡土结构墙背条件下，用最小抗倾覆安全系数来研究挡土墙后土体的破坏机制较为合理。 |
| 9. | It was shown that when the soil pressure on the stepped rsrw was relatively small , its distribution form was zigzag , and would be affected evidently by unloading function of the step ; the potential fracture surface of the stepped rsrw was obviously different from the 0 . 3h fracture surface proposed by the usual hypothesis , and would change with height - width ratio of the wall ; finally , its deformation characteristics were different from the vertical rsrw with single step
测试表明：台阶式加筋土挡墙的墙后土压力较小，呈锯齿形分布，明显受台阶卸载的影响；潜在破裂面与0 . 3h破裂面假定有较大差异，并随挡墙的高宽比变化而变化；变形特征不同于单级直立式挡墙。 |
| 10. | Third , it puts forward the logarithmic spiral failure surface bishop steep reinforced slope limit equilibrium stability analysis method . this method is used to calculate the engineering living example and compared with the calculations of the engineering living example and compared with the calculations of the swedish circle method and proved applicable
第三，本文针对加筋陡坡潜在破裂面矢径随路堤深度而增加的特点，提出用对数螺旋线作滑动面的毕肖普法进行稳定分析，编制了稳定分析程序，并对工程实例进行了分析计算，将计算结果与瑞典圆弧法分析进行比较。 |
