Research methods:By using structural analysis to find the control factors in the design of the shed hole structure and aiming at these control factors to compare the several different shed hole structure designments,the better designment can be confirmed.

• 研究方法:通过结构计算分析棚洞结构设计的控制因素,针对控制因素对棚洞结构方案进行研究比选,确定棚洞的结构方案。
