发布时间：2018-07-31 18:27

【摘要】：在山区的输电线路中,为了响应国家及国家电网对于环境保护的要求,设计院需要对铁塔进行长短腿、对铁塔基础进行高低基础的相应设计,从而更好的适应塔位地形,减少开挖基础对塔位原状土的大面积破坏。但是,同样的塔位地形可以有多种长短腿与高低基础的配置方案,设计者无法在没有相关定性及定量的情况下,将各种方案一一考虑。通常只能凭经验及现场情况给出相应的配置方案。虽然他们都能在一定程度上满足工程要求,但是其配置方案所对应的基础开挖量及基础本身的经济指标(基础混凝土、基础钢材、基础挡土墙体积等)可能并不是最优化的。故此,本文研究的目的是寻找可以通过定性及定量的方法(逻辑公式),从而优化输电线路在山区工程所使用的长短腿铁塔及高低基础的相互配置,以达到在塔位不变的情况下,基础材料用量最小、基础基面铲挖量最小,从而更好的保护塔位所在区域的地理环境,也能在一定程度上控制基础的材料量,降低工程总投资。本文给出的逻辑公式内容既要满足铁塔基础设计时抗上拔要求,又要满足实际工程的相关设计习惯。本文研究的逻辑公式不是通常的线性数学公式,而是基于塔位基面的测量数值,通过特殊的排列、逻辑计算后形成的流程图。它可以一次原始数据输入,根据不同的判断语句输出多个计算结果以供设计者选择。本文给出的逻辑公式可以用现行的计算机语言(C++、JAVA、VBA等)编写,形成可执行程序,方便设计者使用。本文进行了实际工程的方案优化与实际方案的对比,虽然该比较结果并不能完全说明优化结果一定会在实际工程中起到明显的作用。但是,通过对每一基塔位的优化配置,完全可以使得整个工程基础材料量和铲挖量得到有效地控制及减少,从而更好地保护环境,促进电网工程健康发展。
[Abstract]:In order to respond to the requirements of the state power grid for environmental protection in the mountainous areas, the design institute needs to design the tower's long and short legs and the high and low foundation of the tower foundation, so as to better adapt to the tower terrain. Reduce the large area damage to tower undisturbed soil caused by excavation foundation. However, the same tower terrain can have a variety of long and short legs and high and low base configuration schemes, designers can not be related to the qualitative and quantitative situation, the various schemes are considered. Usually only based on experience and field conditions to give the corresponding configuration. Although they can meet the engineering requirements to a certain extent, the amount of foundation excavation and the economic index of the foundation itself (foundation concrete, foundation steel, foundation retaining wall volume, etc.) corresponding to its configuration scheme may not be optimized. Therefore, the purpose of this study is to find out whether qualitative and quantitative methods (logical formulas) can be used to optimize the mutual configuration of long and short legged iron towers and their high and low foundations used by transmission lines in mountain area projects, so as to achieve the same tower position. The minimum amount of foundation material and the minimum amount of foundation shovel can better protect the geographical environment of the area where the tower is located and to a certain extent control the amount of foundation material and reduce the total investment of the project. The logical formula given in this paper not only meets the requirements of anti-uplift in the design of iron tower foundation, but also meets the relevant design habits of practical engineering. The logic formula studied in this paper is not a usual linear mathematical formula, but a flowchart based on the measurement value of the tower base plane, and through special arrangement and logical calculation. It can input raw data at a time and output multiple results according to different judgment statements for designers to choose. The logic formula given in this paper can be written in the current computer language (C / Java VBA et al.) to form an executable program, which is convenient for designers to use. In this paper, the comparison between the scheme optimization of practical engineering and that of actual project is carried out, although the comparison results do not completely show that the optimization results will play an obvious role in practical engineering. However, by optimizing the configuration of each base tower, the quantity of foundation material and shovel can be effectively controlled and reduced, so as to better protect the environment and promote the healthy development of power grid engineering.
