基于某地铁隧道与上方高层建筑共建方案，借助于 Midas GTS 大型岩土仿真软件，针对地铁隧道与高层建筑地下室结构合建、分离两个方案进行研究，对比分析了地铁明挖隧道的内力与位移情况。研究表明：高层建筑施工会导致基坑底部以下地层产生明显的沉降变形；结构合建方案会导致下方明挖隧道产生显著的附加应力与变形，对结构承载力与稳定性产生较大影响；而结构分离方案则能利用地下室底板下设置的转换体系将高层建筑附加荷载有效地传递到地层深处，进而有效地减小下方明挖隧道的附加应力与变形。研究结论可为类似工程提供借鉴与参考。
基于某地鐵隧道與上方高層建築共建方案，藉助于 Midas GTS 大型巖土倣真軟件，針對地鐵隧道與高層建築地下室結構閤建、分離兩箇方案進行研究，對比分析瞭地鐵明挖隧道的內力與位移情況。研究錶明：高層建築施工會導緻基坑底部以下地層產生明顯的沉降變形；結構閤建方案會導緻下方明挖隧道產生顯著的附加應力與變形，對結構承載力與穩定性產生較大影響；而結構分離方案則能利用地下室底闆下設置的轉換體繫將高層建築附加荷載有效地傳遞到地層深處，進而有效地減小下方明挖隧道的附加應力與變形。研究結論可為類似工程提供藉鑒與參攷。

Based on the co-construction project of the subway tunnels and the upper high-rise buildings ,the co-construc-tion and the separate-construction schemes of the subway tunnels and the basements of the upper high-rise buildings were investigated and analyzed with midas GTS ,as well as the stress and deformation field of the subway tunnels .The analysis indicates that the construction of the high-rise buildings will lead to an obvious settlement of the bottom of the pit ;the co-construction scheme will cause remarkable additional stress and deformation for the subway tunnels below and a major im-pact on the capacity and stability of the upper high-rise buildings ;whereas the separate-construction scheme can effec-tively reduce the additional stress and deformation of the subway tunnels below by using the transfer system under the basement floor to transmit the additional load of the high-rise building to the deeper layers .The research conclusion can provide some reference for similar projects .
