摘要
混凝土挡土墙在工程中应用广泛,但是设计人员往往重视不够,通过对实际工程中的地下车库外侧天井结构方案比选确定采用混凝土挡土墙结构为最优结构方案,从而引入对混凝土挡土墙设计工作的具体分析,列举了挡土墙计算简图选取的误区以及施工方式对结构计算简图的影响,工程师要考虑施工对结构受力最不利情况,同时应在设计文件中对施工提出合理要求。通过设置挡土墙基础结构拉梁的方式在不影响其他专业的前提下确保结构挡土墙稳定性并且满足天井结构抗浮要求,利用挡土墙受力弯矩图节省结构材料达到降低工程造价的目的,结构师采用结构计算理论应符合工程实际情况,脱离实际的理论计算会对工程造成安全隐患。并建议利用计算机辅助设计的方法提高设计人员的工作效率,最终得到获得业主满意的工程。
Concrete retaining wall is widely used in engineering,but designers often pay less attention to it.In this paper,the concrete retaining wall structure is determined to be the optimal structural scheme through comparison and selection of the outer patio of the underground garage in the actual project,so as to introduce the specific analysis of the design work of the concrete retaining wall,and enumerate the errors in the selection of the calculation diagram of the retaining wall and the influence of the construction method on the structure calculation diagram,The engineer shall consider the most unfavorable conditions for the structure and put forward reasonable requirements for construction in the design documents.The structural calculation theory adopted by the structural engineer should conform to the actual situation of the project,and the theoretical calculation divorced from the actual situation will cause safety hazards to the project.It is suggested to use the computer-aided design method to improve the working efficiency of engineers and finally obtain the project satisfying the owner.
