Of all the integral stability evaluation methods , the finite element method ( fem ) is adapted to homogenous , isotropic linear elastic mass which has small deformation . in application , fem neglects various structure faces which control integral stability of rock slopes 在现有的岩质边坡整体稳定性评价方法中,有限元数值模拟( fem )适合于均质、各向同性、小变形的线弹性体,在应用中,没有考虑到对岩质边坡的整体稳定性起控制作用的各种结构面。
In this thesis , studies are focused on as follows : ( 1 ) based on analyzing the general transfer - matrix , the conception of the generalized double layer soil model is proposed , and the transfer - matrix ( r ) of half - infinite elastic mass is introduce - d to the analytic expressions of stress and settlement under the uniform circular , rectangular and strip vertical loads in multi - layered soil ; ( 2 ) according to the analytic expressions of the additional stress and settlement under unifo - rm circular in multi - layered soil , rectangular and strip vertical loads , the programs are develop - ed to resolve and debugged . the results show that the programs are correct ; ( 3 ) through calculating the coefficient of additional stress on the central axis of uniform circ - ular vertical loads , under the corner point of the uniform rectangular vertical loads , and on the central axis of uniform strip vertical loads , and the settlement on the center of uniform circular vertical loads and uniform rectangular loads in double - layered soil , the characters of stress and settlement are discussed ; ( 4 ) a case , as an example , is studied with different calculation methods , such as traditional theory , fem . the results obtained are compared 本文在已有研究成果的基础上进一步开展了以下几方面的研究: ( 1 )在对层状地基传递矩阵法中的总传递矩阵分析的基础上,提出了广义双层地基模型的概念,并把半无限体的传递矩阵r引入到多层地基在圆形垂直均布荷载、矩形垂直均布荷载及条形垂直均布荷载作用下附加应力与沉降的解析式中; ( 2 )根据多层地基在圆形荷载、矩形垂直均布荷载及条形垂直均布荷载作用下附加应力与沉降的解析式,编制了程序,调试通过并验证了其正确性; ( 3 )通过对双层地基圆形垂直均布荷载中心轴线上的附加应力系数和荷载中心沉降,矩形垂直均布荷载角点下的附加应力系数和荷载角点沉降及条形垂直均布荷载中心轴线上的附加应力系数进行的计算,探讨了双层地基中的附加应力与沉降特性; ( 4 )应用本文的层状地基体系理论对一个工程实例进行了计算分析,并与传统的计算方法的计算结果和有限单元方法的计算结果进行了对比分析,结果表明利用层状地基理论计算更能反映地基中附加应力分布的实际情况。
The rule of settlement and pore stress is educed too . then it is compared with the case which is found in site . finally , the paper studies the computing method of pile to soil stress ratio of rigid pile composite foundation with cuhion , and these conditions are thought that the top of pile pierce into cushion and the bottom of pile pierce into underlayer . lt is assumed that the cushion is ideal elastic mass and ideal elastic - plastic mass , then the formula is developed and all parameters " effects to stress ratio of pile to soil are discussed 最后,推导出了带垫层的刚性桩复合地基桩土应力比的计算公式,这个公式将垫层分为弹性体和理想弹塑性体两种情况分别进行推导,考虑刚性桩刺入垫层和下卧层的情况,并对公式进行了分析,得出了在刚性桩复合地基中桩土应力比随着垫层模量和桩模量的增大而增大,但都有一极限值,随桩间土模量的增大而减小,也有一极限值。
