［摘要］周圍地下空間開發(fā)結(jié)構(gòu)與地鐵車站連通形成地下綜合體，在其相連接側(cè)墻上進(jìn)行開孔以方便通行，但開孔必定會(huì)對(duì)結(jié)構(gòu)抗震性能產(chǎn)生影響，因此有必要分析其地震響應(yīng)。以實(shí)際工程為背景，建立結(jié)構(gòu)三維模型，分析不同開孔方式對(duì)結(jié)構(gòu)地震響應(yīng)的影響，確定地下結(jié)構(gòu)空間效應(yīng)以及抗震薄弱部位。分析結(jié)果表明：地下綜合體中車站部分的層間位移角、柱端水平彎矩等響應(yīng)均大于相應(yīng)的標(biāo)準(zhǔn)車站，表明側(cè)向開孔削弱了結(jié)構(gòu)的整體剛度，降低了其抗震性能，但不同開孔方式對(duì)結(jié)構(gòu)地震響應(yīng)的影響并不明顯。

Abstract:The surrounding underground space development structure is connected with the subway station to form an underground urban complex, and openings are made on the connected side walls to facilitate people’s access. Openings must have an impact on the seismic performance of the structure, so it is necessary to analyze the seismic response. Based on the actual engineering background, the three-dimensional model was established, the influence of different opening methods on the seismic response of the structure was analyzed, and the spatial effects of the underground structure and the weak parts of the earthquake were determined. The  analysis shows that the response angles of the interlayer displacement and the horizontal bending moment at the column end of the underground urban complex are larger than the corresponding standard stations, indicating that the lateral openings weaken the overall stiffness of the structure and reduce its seismic performance. But the influence of different opening methods on the seismic response of the structure is not obvious.

Keywords:continuous openings on lateral wall;underground urban complex;seismic response;spatial effect;seismic performance
