基于遗传算法的深基坑桩锚支护结构的设计优化与MATLAB实现

深基坑设计的总原则为安全、经济、方便施工。深基坑工程是一个综合性跨学科难题,其中涉及到强度、稳定、变形、渗流等问题。一个成功的基坑设计,必须兼顾以上各因素,并将工程勘察、支护设计、施工管理、现场监测、动态分析等各项工作紧密结合。在总结有关文献的基础上,以深基坑桩锚支护结构的设计为主线,对深基坑桩锚支护结构的从计算理论到优化过程进行全面分析和对比优选,总结出一条切实可行的计算、优化途径并进行了程序化实现。

Calculation and Optimization of Deep Excavation Pit-anchor Retaining Structure

The key principle of the design of deep excavation retaining structure are safety,economic and available to construction.The deep excavation engineering is a problem of comprehensive and cross-disciplinary,which refers to strength,stability,deformation,seepage and so on.A successful evacuation design should consider these factors above and combine the work of engineering reconnaissance,retaining design,construction management,scene monitor and dynamic analysis.Except of summarizing referring documents,the main thread of this paper is the design of deep evacuation pit-anchor retaining structure.Through the comprehensive analysis and optimization of the pit-anchor retaining structure from calculating theory to optimization,we summarize a practical calculating and optimization procedure.
