摘要：设计范围为贵阳市轨道交通2号线二期工程富源北路站～森林公园站区间暗挖隧道，设计起讫里程为:YCK39+020.35~YCK42+058.88（YCK40+003.206= ZCK40+000.000 长链3.206m）， ZCK39+020.35~ZCK42+059.6（ZCK40+005.202=ZCK40+000.000 长链5.202m），右隧全长3041.056m，左隧全长3043.052m。线间距为12～16m，隧道拱顶埋深15～220m，在富源北路站端设置停车线。其中YCK39+057～+109、YCK39+304～+370、YCK39+509～+575为停车线4线大断面结构，其余段为单洞双线+双洞单线结构。 67743

本设计按照矿山法的施工要求，对停车线4线大断面结构进行综合设计。内容主要包括：隧道的平纵断面线型设计、隧道净空断面设计，隧道衬砌结构设计以及施工组织设计等。并利用ANSYS软件，进行了结构内力的计算。

本设计采用复合式衬砌，利用双侧壁导坑法进行开挖，进行科学施工管理。经过验算，该隧道方案设计合理，衬砌结构配筋验算均满足要求。

Design of single tunnel 4 line in Fusen section of Guiyang Light Rail Line

Abstract：The design range for the Guiyang City Rail Transit Line 2 Phase II project Fuyuan North Road Station ~ Forest Park Station area under the tunnel, Design mileage is: YCK39 + 020.35 ~ YCK42 + 058.6 (ZCK40 + 003.206 = ZCK40 + 000.000 long chain 3.206m), ZCK39 + 020.35 ~ ZCK42 + 059.6 (ZCK40 + 005.202 = ZCK40 + 000.000 long chain 5.202m), the right tunnel length is 3041.056m. Line spacing of 12 ~ 16m, tunnel dome depth of 15 ~ 220m, in Fuyuan North Road Station side set the parking line. YCK39 + 057 ~ +575, YCK39 + 304 ~ +440, YCK39 + 509 ~ +575 for the parking line 4 large cross-section structure, the rest of the single-hole double-track + double-hole single-line structure, using mine construction. 

The design of the mine in accordance with the requirements of the construction of the parking line 4 large cross-section structure of the comprehensive design.The main contents of this design include: tunnel vertical profile design, tunnel clearance design, tunnel lining structure design and construction organization design. And using ANSYS software, the structure of the secondary lining is calculated.

The design uses a composite lining, Using the double-wall guide pit method for excavation, and construct scientific management. After checking, the tunnel program design is reasonable, lining structural reinforcement check to meet the requirements.

KeyWords: Mine method; composite lining; ANSYS; double side wall guide method
