【摘要】：随着我国交通建设事业的蓬勃发展,大量的公路、铁路和机场等基础设施建设进入山区,深挖高填现象往往引发大量的工程滑坡,这必将严重制约工程建设的发展。这类工程滑坡治理的投资规模巨大,这使得滑坡治理工程效果评价变得尤为重要。基于上述考虑,本文以滑坡治理工程效果评价体系的建立和应用为主线,以已整治的重庆奉云路挖断村滑坡治理工程为背景,开展滑坡治理工程效果评价的研究,基于Excel VBA开发了滑坡治理工程效果评价系统。论文的主要研究内容和结论包括以下几个方面:(1)初步建立了一套滑坡治理效果评价指标体系:在借鉴前人的研究成果基础上,采取多种方式征求滑坡专家意见,初步建立了滑坡治理工程评价指标体系。(2)依托指标体系对挖断村滑坡的治理效果进行系统评价:通过对挖断村滑坡的工程勘察、工程设计及工程实施的安全性、合理性、经济性进行系统分析,表明该滑坡整体治理效果良好,坡体逐渐趋于稳定,主体抗滑支挡结构工作状态正常,但个别结构存在损坏现象,应引起运营主管部门的高度重视。(3)总结出了挖断村滑坡治理工程中一些特色的新技术、新工艺:在挖断村滑坡治理中,采用“一次根治、分期落实”的治理措施理念,提高了施工效率和效果,降低了工程造价。同时,动态设计、信息化施工也是该滑坡治理工程的一大特色,有效推进了后续工程施工。(4)基于Excel VBA开发了滑坡治理效果评价系统:该系统具有信息全面、操作方便快捷、基础理论成熟的特点。利用该系统对挖断村滑坡治理工程进行了分析评价,得出评价结果与实际工程分析结论较为相符。通过以上效果评价方法,验证了所提出的挖断村滑坡治理工程效果分析结论的正确性,表明了基于Excel VBA的滑坡治理工程效果评价系统的可靠性。该评价方法不仅在奉节地区以及三峡库区众多复杂堆积层滑坡的治理过程中得以广泛应用,而且在西南复杂的地质环境下的交通工程建设也起到借鉴作用。本文的研究方法和成果必将对我国交通系统的地质灾害(特别是滑坡)治理工程效果评价工作提供借鉴和参考,客观公正的看待已经完成的病害治理工程,用以指导和优化病害的防治,减少灾害损失。
[Abstract]:With the vigorous development of traffic construction in our country, a large number of infrastructure construction such as roads, railways and airports have entered the mountainous areas. The phenomenon of deep digging and filling often leads to a large number of engineering landslides, which will seriously restrict the development of engineering construction. This kind of engineering landslide treatment investment scale is huge, which makes landslide treatment engineering effect evaluation become particularly important. Based on the above considerations, this paper takes the establishment and application of landslide treatment engineering effect evaluation system as the main line, taking the renovated Fengyun Road excavated and broken Village landslide treatment Project in Chongqing as the background to carry out the research on landslide treatment engineering effect evaluation. Based on Excel VBA, a landslide control engineering effect evaluation system is developed. The main research contents and conclusions of this paper include the following aspects: 1) A set of evaluation index system of landslide control effect is established preliminarily: on the basis of drawing lessons from previous research results, expert opinions on landslide are sought in various ways. The evaluation index system of landslide control engineering is established preliminarily. (2) based on the index system, the effect of landslide treatment in excavated and broken village is systematically evaluated: through the engineering investigation, the safety of engineering design and the implementation of the project, the rationality is obtained. The system analysis of economy shows that the landslide has good overall control effect, the slope body tends to be stable gradually, and the main body anti-slide retaining structure is in normal working condition, but some structures are damaged. This paper sums up some characteristic new technologies in the landslide treatment project of excavated and broken village. The new technology: in the treatment of the landslide in the excavated and broken village, the idea of "one radical cure, phased implementation" is adopted. The construction efficiency and effect are improved, and the project cost is reduced. At the same time, the dynamic design and information construction are also a major feature of the landslide treatment project, which effectively promotes the construction of the follow-up project. The evaluation system of landslide treatment effect is developed based on Excel VBA. The system has the advantages of comprehensive information and convenient operation. The characteristic of mature basic theory. The system is used to analyze and evaluate the landslide treatment project of excavated and broken village, and the evaluation results are in good agreement with the actual engineering analysis results. Through the above evaluation methods, the correctness of the result analysis conclusions of the landslide treatment project of excavated and broken village is verified, and the reliability of the landslide treatment engineering effect evaluation system based on Excel VBA is proved. The evaluation method is not only widely used in the process of controlling the landslide in Fengjie area and the three Gorges Reservoir area, but also in the traffic engineering construction in the complex geological environment of southwest China. The research methods and results of this paper will provide reference and reference for the evaluation of the effect of geological hazards (especially landslide) control projects in China's transportation system, and objectively and fairly treat the completed disease control projects. In order to guide and optimize the prevention and treatment of disease, reduce disaster losses.
