- Beam on elastic foundation
弹性基础梁 - In this paper , according to the infection line method , the maximal values ( sefflement , shear and moment ) of the tunnel are calculated by using the theory of beams on elastic foundation
本文根据弹性地基梁原理，采用计算各截面的影响线方法，按最不利情况加载，得到了最大的反应值（沉陷、剪力和弯矩） 。 - Though a classic one , the problem of beam on elastic foundation is still in the process of development with the coming forth of new foundation models , new analysis methods and computational means
虽然地基上梁的分析系经典课题，但由于新的地基模型、分析方法和计算手段陆续出现，故该课题至今仍处在发展之中。 - In chapter 2 , proposes an analytical model to the grillage girder , and then establishes its equations by force method . for the primary structure , the upper longitudinal beam is regarded as the finite length continuous girder by elastic point supporting , and the lower cross girder is regarded as the finite length beam on elastic foundation . a computing program is made by qbasic language
第二章主要提出了弹性支承交叉梁系模型，用力法建立了结构静力求解方程，基本结构的处理上，上层纵梁视为有限长点支承连续梁，下层横梁视为有限长弹性地基梁，用qbasic语言编制了求解程序。 - This paper deals with seismic response of a tunnel - soil system immersed tunnel ， as an underground structure ， must be compatible with the deformation of the surrounding soil thus the simplified model for a tunnel - soil system is established through two steps at the first step ， an mdof system is developed for modeling the foundation soil to this end ， dynamic behavior of the foundation soil is analyzed a typical section of the foundation soil simplified as a single mass - spring system on the basis of some equivalent criteria those mass are linked longitudinally by elastic springs to form an mdof system at the second step ， the tunnel is treated as a beam on elastic foundation ; that is ， the tunnel is connected with the soil massed to form a tunnel - soil system this model has been applied to the seismic analysis of huangsha fangcun immersed tunnel across the pearl river in guangzhou design recommendation is proposed on the basis of this analysis
研究沉管隧道在地震条件下整体受力的分析方法分两步建立计算模型第一步通过分析场地地基土切片的动力特性，根据等效原则将其化为等效单质点体系，然后在纵向用等效弹簧连接而成为多质点体系的地基土计算模型；第二步将隧道看作弹性地基梁与上述多质点体系通过等效弹簧连结而得到土隧道体系的计算模型本文结合广州黄沙芳村珠江水下隧道工程实例建立了具体的计算模型并对多种不同的约束条件，进行了纵向与横向地震响应时程分析，为该隧道的抗震设计提供依据
