In addition, no transition arc was machined from the bearing surface of the bolt forehead to the neck scapular root of the screw rod, which leds to the bolt fracture failure also. 另外,螺栓加工头部支承面到螺杆颈部的肩胛根部没有过渡圆弧,也是螺栓断裂失效的一个原因。
On the peak of the part GH and HI., there is a little of soil, will happen soil slide. Height of filling is 2m to 10m, will break and slip alone the rock plane or failure self arc or beeline failure. GH和HI坡顶,局部地方有少量覆土,可能局部发生土溜,还有一些地段存在填方,填方土体高度在2~10m,可能发生沿基岩面的滑移破坏,以及自身的圆弧型及直线型破坏。
Two formulae for shear strength calculation of brick walls arc discussed in the paper. Authors present a new formula based on the analysis of mechanism and diagram for shear failure. 本文讨论了两种砖砌体抗剪强度计算公式,并在分析砖砌体抗剪破坏机理及墙体破坏裂缝图的基础上,提出一种新的抗剪强度计算公式。
By analysing the Chaplin's formula for calculation of pull force of mooring rope, this paper proves the applicability of reasonable determining its pre pull force to prevent variance of rope arc weight in multi-mooring rope system from causing failure of mooring rope and ground anchor. 本文从分析计算缆风绳拉力的查浦林公式入手,论证了合理确定初拉力,防止在多缆风绳受力系统中缆风绳弧垂变化导致缆风绳及地锚失效的可行性;
Some failures are often caused while tungsten-inert-gas arc welding is used by hand in alu-minium alloy equipment of 6000m~ 3,10000m~ 3 air seperation unit and pipeline. This article analyzes the causes in theory and gives the proper failure prevention measures according to welding practice. 本文对6000m~3、1000m~3空分装置铝镁合金设务、管道在采用手工钨极氩弧焊接中常出现的主要缺陷,分析了产生的原因,根据焊接实践经验,提出了相应的避免措施。
Parts AB and DF are the main filling slope, whose failure pattern is self arc failure or beeline failure. AB和DF段主要为填方边坡,边坡的破坏模式为自身的圆弧型破坏或直线型破坏;
Finally, the formation of arc crack and whole failure transitions were explained with the theory of fractural mechanics. 最后进一步的断裂力学理论解释了弧形拉裂与整体贯穿拉裂的形成。研究结果对于工程实际具有一定的现实指导意义。
Numerous case studies are made on slopes to calculate the stability of slopes which have undergone potential arc failure and wedge failure. 以大量的边坡实例为样本,利用该网络,对具有潜在圆弧形破坏和楔形破坏的边坡进行稳定性计算。
Based on the limit equivalence theory and limit analysis theory, the arc oscillatory shear failure models were established, and the results were compared with those of flume test and other theoretical methods. 基于极限平衡法和极限分析法,推导出波浪作用下海床圆弧振荡剪切破坏公式,并与水槽试验结果和其它计算结果比较。
Circuit breaks will be switched on the arc ground fault resulting in the reclosing failure if the secondary arc cannot be extincted in time. 如果潜供电弧不能及时熄灭,将使断路器重合于弧光接地故障,造成重合闸失败。
