半空间体 meaning in English
semi-infinite body
Examples
- This paper ' s mostly content is the theories and methods of designing the rigid pavement plates which traversed by moving load and based on elastic half - space foundations the paper also considering the transfer load of joints . joints merely transfer shearing force and merely transfer moment is respectively considered
本论文主要讨论了在移动荷载作用下，弹性半空间体地基上考虑接缝传荷的刚性道面板的动态设计理论和计算方法，在讨论中分别考虑了接缝单一传递剪力和单一传递弯矩时的两种情况。 - Using the displacement functions and the technique of double fourier transform , the governing differential equations for transversely isotropic saturated poroelastic media are easily solved and , the fourier transformed stress and displacement solutions coorespondingly are obtained . then , under the boundary conditions , the analytical solutions for half - space are presented
借助位移函数及双重fourier变换，研究了直角坐标系下横观各向同性饱和土的动力响应问题，得到了饱和半空间体在任意分布的表面谐振荷载作用下稳态响应的一般解。 - It indicates that although this procedure has introduced the mechanistic - empirical method , but still is not perfect in design theory : one is about bearing capacity evaluation method and device . the currently used device - benkelman beam is dropping behind the development of the pavement testing service ; the other is about the mechanistic method that used in overlay design . it simplifies the original pavement and subgrade as a whole half infinite space , this is not true in the real layered pavement structure
综合分析了各种罩面设计方法的原理及其优缺点，对于我国目前设计规范中所采用的罩面设计方法进行了详细的分析与研究，指出了它虽然已经采用了力学与经验相结合的设计方法，但仍然存在着明显的不足之处：一方面是旧路承载能力评价设备仍然采用贝克曼梁，检测手段落后；另一方面，在力学设计方法中，对于旧路承载能力的评估忽略了旧路面结构的分层，而是采用了近似的弹性半空间体，给出了旧路顶面的综合回弹模量。
