In this paper, a high performance sma system applied to steel bridge deck is put forth in allusion to the pavement project of the wuhan junshan yangtze river highway bridge. it comprises steel slab, zn coating layer, closing layer, adhesive, pre - mixed asphalt stone and dual layer sma from bottom to top. it is based on the fea results of the forces and deformation of the pavement layer by means of the algor feas, according to this bridge ' s traffic and the ambient temperature varying range of the pavement layer
本文針對武漢軍山長江公路大橋鋼箱梁橋面鋪裝工程，從鋪裝層環境溫度變化范圍、交通量等使用條件出發，在用algorfeas有限元分析軟體分析鋪裝層受力變形基礎上，提出了（即鋼板+金屬鋅塗層+封閉層+粘接劑+預拌瀝青碎石+雙層sma ）的高性能鋼橋面sma鋪裝體系，並對這種sma的組成材料，包括改性瀝青、集料、礦粉、纖維進行了比較研究，設計了這種sma的配合比，對sma混合料的性能進行了對比試驗，對這種sma方案進行了疲勞性能研究，驗證了所選擇sma方案的可行性。 -
Before two years passed, the rash pair were both dead, and laid quietly side by side under one slab. i have seen their grave ; it formed part of the pavement of a huge churchyard surrounding the grim, soot - black old daughter, which, at its very birth, charity received in her lap - cold as that of the snow - drift i almost stuck fast in to - night
靜靜地躺在同一塊石板底下我見過他們的墳墓，它在郡的一個人口稠密的工業城市，那裡有一個煤煙一般黑面目猙獰的老教堂，四周被一大片墓地包圍著，那兩人的墳墓已成了墓地人行道的一部份。 -
Meanwhile, the factors causing fissures in the pavement fall into three layers from down to up, namely, the bottom layer of the pavement slab - the formation and fissures & breakage of the transition layer between the pavement and base interface makes the chief reason for the formation of initial cracks and later fissures ; the middle layer - the pavement plate
同時，將路面開裂的影響因素由下而上分為三個不同的層面，即：路面板底層? ?路面與基層界面之間過渡層的形成及其開裂，是導致初始裂縫形成和影響後期開裂的根本原因；中間層? ?路面板體。 -
Through the research and analysis on the three aspects concerning the base interface of the pavement panel, crack accumulation, expansion in the pavement panel and interaction between spring plates on the road surface as well as its damage on the road fatigue, it is first brought forth that the process of fissures and breakage in the cement concrete pavement can be divided into three stages, i. e. stage of initial crack formation and damage in the bottom of the pavement slab, stage of accumulation, intensifying & expansion in ruptures from load during the time of use and stage of fissures & breakage in the pavement
通過對路面板底界面開裂、路面板中裂縫積聚、擴展和路面表面車板相互作用及其對路面疲勞破壞的影響等三個層面的研究和分析，首次提出水泥混凝土路面的開裂和破壞過程可以分為三個階段，即路面板底初始損傷西南交通大學博士研究生學位論文第11頁和早期裂縫的形成階段、使用期間荷載作用對路面造成的開裂損傷累計、加劇和裂縫擴展階段以及路面斷裂破壞階段。 -
On the basis of investigation and analysis, the author, directed against such diseases in cement concrete pavement as rupture, hollow, crack and mud - pumping, presents the measures of replacing the whole slab and filling slurry
在調查分析的基礎上，針對舊水泥混凝土路面板的斷裂、脫空、裂縫和唧泥等病害，提出了整板更換或壓漿灌入等方法。 -
Application of grouting technology pumping and slab hollow problems on cement concrete pavement

Firstly, this paper establishes the contact model of pavement and vehicles, and uses the method of transform domain analysis to get structural characteristic of pavement slab and the relation between suffered loads and its response
本文首先建立了路面-車輛接觸模型，採用變換域分析的方法得到板的結構特性和所受載荷及其響應的關系。 -
Therefore, the present paper, based on the existing achievements as well as an extensive study & investigation in combination with part of the achievements the author has derived by hosting or participating in the research programs of the cement concrete pavement, has led to three phases of fissures and breaking in the pavement slab on the condition that each performance of the subgrade is maintained, i. e. stages of formation in initial cracks, of accumulation & expansion in ruptures and of fissures & breakage in the pavement
為此，本文在已有研究成果的基礎上通過廣泛調研，結合作者近幾年來主持或參加的有關水泥混凝土路面研究課題的部分成果，在路面基層的各種性能得到保障的前提下，通過理論研究和試驗研究，得出路面板的開裂破壞過程分為三個階段，即初始裂縫形成階段、裂縫累積和擴展階段以及路面斷裂破壞階段。
