【摘要】：泥石流是一种严重的自然灾害,采用工程治理是防治手段之一,泥石流拦挡坝是工程防治泥石流的一种重要的结构,本文推广应用新型泥石流拦挡坝。基于ANSYS二次开发技术编写了泥石流拦挡坝设计软件,用以验算重力式拦挡坝。使用UIDL设计菜单,Tcl/Tk绘制输入界面,APDL编写核心算法。计算了基本条件下、冲击条件下和地震条件下的坝体抗滑移、抗倾覆以及地基承载力。用MATLAB编写同样功能的软件计算解析解与ANSYS的有限元解对比。调研泥石流拦挡坝的计算方法,改进后应用于格宾坝、钢管混凝土桩林,编写在Windows下运行的设计软件,并对其进行严格的测试。软件可得出各工况的稳定系数以及基础处的应力,并自动判断是否满足要求。软件非常直观地动态显示坝体截面。计算完成后可将用户设计完成的坝体数据保存为Excel或者CSV格式。接下来可通过AutoCAD自动生成图形。考虑到课题组研发了多种泥石流防治结构,考虑到日后拓展同时为了方便编程,软件采用面向对象的思路开发。修建格宾坝示范工程,本文说明了工程概况,记述了主要设计方法和过程,并设计了监测方案对其监测。对泥石流软件开发模式进行新的探索,使用效果表明设计软件计算结果精确可靠,软件能大大提高设计效率,对其他工程有借鉴意义。
[Abstract]:Debris flow is a kind of serious natural disaster, adopting engineering control is one of the means of prevention and cure, and blocking dam of debris flow is an important structure of engineering prevention and control of debris flow. This paper popularizes and applies a new type of debris flow to block dam. Based on the secondary development technology of ANSYS, the design software of debris flow retaining dam is compiled to check the gravity retaining dam. Use UIDL to design menu and draw input interface with TCL / TK to write the core algorithm. The anti-slip, anti-overturning and bearing capacity of the dam under the basic condition, the impact condition and the earthquake condition are calculated. The analytical solution of the software with the same function is written by MATLAB and compared with the finite element solution of ANSYS. This paper investigates the calculation method of debris flow retaining dam, and applies it to Gebin dam, concrete filled steel tube pile forest, compiles the design software running under Windows, and carries on strict test to it. The software can obtain the stability coefficient and the stress of the foundation, and automatically judge whether to meet the requirements. The software shows the section of the dam dynamically and intuitively. After the calculation is completed, the dam body data designed by the user can be saved as Excel or CSV format. The graphics can then be generated automatically through AutoCAD. Considering the research and development of various debris flow prevention structures in our research group, and considering the future development of debris flow prevention and control structure, and in order to facilitate programming, the software is developed with an object-oriented approach. This paper describes the general situation of the project, describes the main design methods and processes, and designs a monitoring scheme to monitor the project. The application results show that the calculation results of the design software are accurate and reliable, and the software can greatly improve the design efficiency, which can be used as a reference for other projects.
