It is shown in this test study that irregular wave poses greater threat to the stability of toe berm in the front of sloping breakwater than regular wave corresponding to Hs, and that the form of the armor layer also influences the toe berm block stability. 试验研究表明,不规则波对斜坡堤护脚棱体稳定性的威胁大于波高对应于Hs的规则波,斜坡堤护面形式对护脚块石的稳定也有影响。
This article primarily introduces the structural design of a high-rise with irregular horizon-tal and vertical planes and transfer floor, as well as the construction requirements and use status of concrete mold block. 文章着重介绍一幢平、立面均不规则,又有转换层的超限高层建筑的结构设计,以及混凝土模卡砌块的构造要求和使用情况。
The non-neat block stone pavement used by the difference of stone processing and figuring degree is divided into the irregular block stone pavement and half-neat block stone pavement. 非整齐块石路面按所用石块加工修琢程度不同分为不整齐块石路面和半整齐块石路面。
Analyzed the characteristics of HOOPS graphical data structure, designed three types of control point interaction creating patterns, applied segmentation approximation algorithm to implement picking up irregular curves in hull block model, adopted projection algorithm and segmentation approximation algorithm to get the intersection of curve and surface. 依据HOOPS图形数据结构的特点,设计出交互创建点的三种操作方式,实现运用分割逼近算法捕捉分段模型中不规则曲线,采用投影算法和分割逼近法求曲线与平面的交点。
The differences of the destruction-resistant mechanics properties between standard and natural samples of ore blocks studied in the dissertation are tested. The test result shows that average compressive strength of the irregular block samples is merely that of 42.88 percent of the standard ones. 针对本论文所研究的矿石,测定了标准试件矿块与自然矿块的抗破坏特性的力学性能差异,其结果是:不规则矿块的抗压强度仅为规则试件抗压强度的42.88%。
