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 在現有的巖質邊坡整體穩定性評價方法中,有限元數值模擬( fem )適合于均質、各向同性、小變形的線彈性體,在應用中,沒有考慮到對巖質邊坡的整體穩定性起控制作用的各種結構面。
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礎上進一步開展了以下幾方面的研究: ( 1 )在對層狀地基傳遞矩陣法中的總傳遞矩陣分析的基礎上,提出了廣義雙層地基模型的概念,并把半無限體的傳遞矩陣r引入到多層地基在圓形垂直均布荷載、矩形垂直均布荷載及條形垂直均布荷載作用下附加應力與沉降的解析式中; ( 2 )根據多層地基在圓形荷載、矩形垂直均布荷載及條形垂直均布荷載作用下附加應力與沉降的解析式,編制了程序,調試通過并驗證了其正確性; ( 3 )通過對雙層地基圓形垂直均布荷載中心軸線上的附加應力系數和荷載中心沉降,矩形垂直均布荷載角點下的附加應力系數和荷載角點沉降及條形垂直均布荷載中心軸線上的附加應力系數進行的計算,探討了雙層地基中的附加應力與沉降特性; ( 4 )應用本文的層狀地基體系理論對一個工程實例進行了計算分析,并與傳統的計算方法的計算結果和有限單元方法的計算結果進行了對比分析,結果表明利用層狀地基理論計算更能反映地基中附加應力分布的實際情況。
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,推導出了帶墊層的剛性樁復合地基樁土應力比的計算公式,這個公式將墊層分為彈性體和理想彈塑性體兩種情況分別進行推導,考慮剛性樁刺入墊層和下臥層的情況,并對公式進行了分析,得出了在剛性樁復合地基中樁土應力比隨著墊層模量和樁模量的增大而增大,但都有一極限值,隨樁間土模量的增大而減小,也有一極限值。
