一种明挖电缆隧道三(四)通结构的简化计算方法

A Simplified Calculation Method of Three(Four)-way of Open Cut Cable Tunnel

结合某电缆隧道工程的实际情况,分析三(四)通结构三维计算模型和二维计算模型受力特性,提出一种简化三(四)通结构的计算方法,经过计算和对比分析,说明该方法可应用于三通结构电缆隧道可研或者初步设计的工程量估算,以及四通结构电缆隧道的施工图设计。

Combined with the actual situation of a cable tunnelproject, this paper analyzes of mechanical properties of three（four）-way structure 3D calculation model and 2D calculationmodel,A simplified calculation method of three （four）-waystructure. The calculation and comparative analysis, illus-trates the three-way structure of cable tunnel and the methodcan be applied to the feasibility study or the preliminary de-sign of the project estimation,for the foure-way structure ofcable tunnel and the method can be applied to the construe-tion drawing design.
