［摘要］媯汭劇場混凝土工程部分包括半地下室工程和舞臺工程兩個部分，半地下室工程主要由一條南北向穿行于蝶狀屋面中部的混凝土連橋及橋面板下部設(shè)置的少量半地下室空間構(gòu)成，選用剪力墻結(jié)構(gòu)體系；舞臺工程包括舞臺臺倉配電室等部分，分別選用框架結(jié)構(gòu)體系和剪力墻結(jié)構(gòu)體系。主要針對混凝土工程的設(shè)計分析重點進行研究：首先，結(jié)合建設(shè)場地地質(zhì)條件和荷載條件，對半地下室工程的地基基礎(chǔ)方案及主要設(shè)計措施進行了具體說明；隨后，重點介紹了半地下室工程中大跨度混凝土拱的設(shè)計計算方法及設(shè)計保證措施；最后，對舞臺結(jié)構(gòu)設(shè)計的關(guān)鍵技術(shù)問題進行了簡要說明。研究及設(shè)計結(jié)果表明：通過合理的結(jié)構(gòu)選型及系統(tǒng)的設(shè)計保證措施，本工程半地下室工程及舞臺工程部分的設(shè)計方案可以較好地滿足結(jié)構(gòu)安全性要求及結(jié)構(gòu)合理性要求，結(jié)構(gòu)安全、可靠，結(jié)構(gòu)設(shè)計可行。

Abstract:The concrete engineering part of Guirui Theater consists of two parts including semi-basement engineering and stage engineering. Semi-basement engineering is mainly composed of a north-south concrete bridge passing through the middle of butterfly roof and a small amount of semi-basement space under bridge deck. It adopts shear wall structural system. Stage engineering includes stage warehouse distribution room and other parts. The frame structure system and the shear wall structure system are selected respectively. The design and analysis of the concrete projects were studied. Firstly, combined with the geological conditions and load conditions of the construction site, the foundation scheme and main design measures of the semi-basement engnieering were described in detail. Secondly, the design calculation method and design assurance measures of large-span concrete arch in semi-basement engnieering were mainly introduced. Finally, the key technical problems of stage structural design were briefly explained. The research and design results show that through reasonable structural selection and system design assurance measures, the design scheme of the semi-basement engnieering and stage engnieering can well meet the structural safety requirements and structural rationality requirements. The structure is safe and reliable, and the structural design is feasible.
