【摘要】：目前地鐵車站作為上部高架橋梁箱型基礎(chǔ)的案例并不多見(jiàn),國(guó)內(nèi)外對(duì)“站橋合一”結(jié)構(gòu)體系的研究大多是抗震方面,而“站橋合一”結(jié)構(gòu)體系的受力與穩(wěn)定性方面研究較少。針對(duì)這一現(xiàn)狀,文章基于廈門市地鐵T型換乘車站(呂厝站)與市政高架橋梁合建工程,通過(guò)建立其有限元分析模型,對(duì)高架橋梁荷載下的地鐵車站結(jié)構(gòu)的受力和穩(wěn)定性方面進(jìn)行了研究,本文的主要內(nèi)容如下:1、根據(jù)現(xiàn)場(chǎng)施工情況以及相關(guān)參數(shù),利用Midas軟件建立地鐵車站二維模型得出車站頂板位置和側(cè)墻位置的最不利點(diǎn);并結(jié)合現(xiàn)行規(guī)范,利用車站最不利點(diǎn)位置所得到的結(jié)果對(duì)車站頂板和側(cè)墻的穩(wěn)定性進(jìn)行了理論分析。2、根據(jù)實(shí)際工程資料,基于有限元軟件ABAQUS建立“站橋合一”結(jié)構(gòu)體系的二維平面應(yīng)變模型,分別考慮在車站結(jié)構(gòu)底部有樁和無(wú)樁兩種工況下,計(jì)算了地鐵車站結(jié)構(gòu)受力性狀,土體沉降,樁側(cè)摩阻力分布規(guī)律等,并對(duì)比分析了這兩種工況下車站模型內(nèi)力,位移等的不同。3、基于ABAQUS有限元軟件,建立“站橋合一”結(jié)構(gòu)體系三維空間模型,對(duì)高架橋梁荷載下的地鐵車站土體位移、各層板的內(nèi)力、以及車站底部樁基位移等進(jìn)行了分析,并與車站底部無(wú)樁工況下作對(duì)比分析。4、對(duì)二維模型和三維模型,在后處理中通過(guò)輸出最大主應(yīng)力值,得到地下結(jié)構(gòu)容易受拉破壞區(qū)域,這對(duì)實(shí)際工程中地下結(jié)構(gòu)配筋設(shè)計(jì)有重要的指導(dǎo)意義。
[Abstract]:At present, there are few cases of subway station as the box foundation of the upper elevated bridge. Most of the researches on the structural system of "the integration of station and bridge" are aseismic, while the research on the stress and stability of the "station and bridge in one" structure system is less. In view of this situation, based on the joint construction of T type transfer station (Lv Cuo Station) and municipal elevated bridge in Xiamen City, the finite element analysis model is established. The stress and stability of subway station structure under elevated bridge load are studied. The main contents of this paper are as follows: 1. According to the construction situation and related parameters, Using Midas software to establish a two-dimensional model of subway station to obtain the most disadvantageous points of the position of the roof and side wall of the station, and combined with the current code, The stability of the roof and side wall of the station is theoretically analyzed by using the results obtained from the position of the most disadvantageous point of the station. According to the actual engineering data, the two-dimensional plane strain model of the "station and bridge in one" structure system is established based on the finite element software ABAQUS. Under the conditions of pile and no pile at the bottom of the station structure, the stress characteristics, soil settlement, friction distribution of pile side and so on are calculated, and the internal forces of the station model are compared and analyzed. Based on the finite element software of ABAQUS, the three-dimensional spatial model of "station and bridge in one" structure system is established. The displacement of soil mass, the internal force of each layer plate and the displacement of pile foundation at the bottom of the station are analyzed under the load of elevated bridge. And compared with the bottom of the station under the condition of no pile. 4, for the two-dimensional model and the three-dimensional model, through the output of the maximum principal stress value in the post-processing, the area where the underground structure is vulnerable to tensile damage is obtained. This is of great significance to the design of reinforcement for underground structures in practical engineering.
