論文中文摘要:本研究係針對建築基礎深開挖,基地周圍鄰房對擋土壁體及地層變形之影響,係採取結構物加載之型式,考量鄰房地下室之影響,採用有限元素法軟體PLAXIS 3D 2017.0,分析鄰房結構體對深開挖工程之影響,模擬順打工法,以版元素模擬連續壁擋土措施,H型鋼組裝完成之支撐構件,以錨桿施加預力模擬,形成建築深開挖之臨時擋土支撐安全措施,鄰房結構則採版元素模擬。
研究結果顯示,擋土壁體側向位移量隨著鄰房地下室深度而改變,地下室深度約為0倍開挖深度,其位移量相對的較大,隨著深度遞增約1倍開挖深度,其位移量趨近於一定值。當鄰房距離擋土壁體約2倍開挖深度,壁體變形曲線收斂,亦即鄰房超過2倍開挖深度之距離,對擋土壁體變形分析而言,可省略2倍開挖深度距離外之鄰房對擋土壁體的影響。當鄰房與擋土壁體的距離約為1倍開挖深度以內,最大側向位移量之深度,隨著距離越接近擋土壁體,其位置越接近地表面,當鄰房離擋土壁體超過1倍開挖深度,最大側向位移量之位置約位於開挖面。
地表沉陷量隨著鄰房地下室深度遞增至開挖深度之一半,其沉陷量相對的較大,隨著深度遞增約1.6倍開挖深度,其沉陷量趨近於一定值。當鄰房離擋土壁體越近,地表沉陷量相對的較大,當鄰房遠離擋土壁體,地表沉陷量相對的較小。
論文英文摘要:This study is based on the deep excavation of the building foundation, the influence of the adjacent rooms around the base on the retaining wall and the deformation of the stratum. The type of structural loading is adopted, considering the influence of the adjacent basement, using the finite element method software PLAXIS 3D 2017.0, analysis The influence of the adjacent house structure on the deep excavation project, simulating the smoothing method, simulating the continuous wall retaining measures with the plate elements, and the supporting members assembled by the H-shaped steel, using the anchor to exert the pre-force simulation to form the temporary deep excavation of the building. The retaining support safety measures, the adjacent room structure is simulated by the plate elements.
The results show that the lateral displacement of the retaining wall changes with the depth of the adjacent basement. The depth of the basement is about 0 times the depth of excavation. The displacement is relatively large, and the depth is about 1 times the depth of excavation. The displacement amount approaches a certain value. When the adjacent room is about 2 times excavation depth from the retaining wall, the wall deformation curve converges, that is, the distance of the adjacent room exceeds 2 times of the excavation depth. For the analysis of the deformation of the retaining wall, the excavation can be omitted. The influence of the adjacent room outside the depth on the retaining wall. When the distance between the adjacent room and the retaining wall is about 1 times the depth of the excavation, the depth of the maximum lateral displacement is closer to the surface of the retaining wall as the distance is closer to the ground surface. The wall has more than 1x excavation depth, and the position of the maximum lateral displacement is located at the excavation surface.
The surface subsidence increases with the depth of the adjacent basement to one-half of the excavation depth, and its subsidence is relatively large. As the depth increases by about 1.6 times, the subsidence is closer to a certain value. When the adjacent house is closer to the retaining wall, the surface subsidence is relatively larger. When the adjacent house is far away from the retaining wall, the surface subsidence is relatively small.
