摘要
以淄博市桓台县工业街、一中西路综合管廊工程为例,分析了吊装口中板开洞长度、侧壁厚度对中板结构受力的影响规律;通过常规二维框架方法和三维框架方法的计算结果对比,验证了常规二维框架方法的合理性。其结果表明,中板开洞越长,则弯矩越大;侧壁越厚,其分担的内力就越多;常规二维框架方法能够满足结构安全性要求,但相对保守。
Taking the utility tunnel project of Gongye street and Yizhong West Road of Huantai County in Zibo City as an example,the influence law of the opening length and the thickness of the side wall on the internal force of the middle plate structure is analyzed;The rationality of conventional 2 D calculation is verified by comparing the calculation results of conventional 2 D calculation method and 3 D one.The results show that the longer the opening is,the greater the bending moment is;The thicker the side wall is,the more internal forces it shares;The conventional 2 D calculation method meets the structural safety but is relatively conservative.
