摘　　要：根据杭州市4000多个综合钻孔资料,利用MapX组成的计算机虚拟场地,并在其上集成了ABAQUS等成熟的计算机软件,对正在建设的杭州市地铁1#线上任意处,在计算机上点击鼠标后,即进行隧洞、衬砌的应力、应变分析与地面沉降计算。由于分析、计算能随时随地地快速进行,故能同监理数据对照。对保证工程安全施工有较大的裨益。According to the data from more than 4000 synthetic boreholes of Hangzhou, the computer virtual site is attained by applying MapX, to which ABAQUS and some other mature softwares are integrated. Stress-strain analysis of the tunnel and lining is carried out, and the calculation of ground surface subsidence at any point on metro line No. 1 can be done after clicking the mouse. For reason that the calculation and analysis can be promptly proceeded at any time and any where with an instant comparison with monitoring data, from which the safe construction benefits much.
