【摘要】：在公路工程建设中,软土地区上的高等级公路由于软土的性质极为复杂,潜在的因素对交通运输带来了严重的灾害,为确保路堤稳定和工后沉降的要求,必须进行稳定和沉降动态观测。一方面是指导施工和验证设计的重要手段；另一方面是进行沉降预测、调整填土计划和确定预压稳定后路面动工时间的重要依据。这也是目前公路工程研究上的最受人关注的的难点之一。因此,对软土地基的变形进行监测和预测,具有重要的理论和实际意义。目前,软土地基监测数据大都是运用excel软件进行处理。、其缺点是计算工作量大,数据管理比较困难以及信息化程度低,这些不便于实际工程的应用。同时,面对大量的施工监测数据,采用传统的方法处理比较复杂,并且工作效率也很低,有时因为不可避免地人为因素,导致数据错误。除此以外,对监测数据结果的分析和数据的运用也比较单调、零碎、很难智能化地有效利用。基于这些问题,本文提出了建立软基监测数据处理预报系统,应用数据库来管理和处理大量的现场监测数据,从而有效提高软基监控的效率。本文首先介绍了软土的相关知识,然后详细介绍了东莞市西部干道监控方案的设计。通过对现场监测数据结果的分析以及沉降预测理论的研究,总结出了软基沉降规律。运用Visual Basic6.0程序设计语言编程衔接各软件及数据库运行整个软件系统。结果表明,软基数据处理预报系统界面友好,应用简单,数据处理效率高,便于实际的工程应用。
[Abstract]:In the construction of highway engineering, the high grade highway in soft soil area is very complicated because of the nature of soft soil, and the potential factors have brought serious disaster to traffic and transportation, in order to ensure the stability of embankment and the requirement of post-construction settlement. Dynamic observation of stability and settlement must be carried out. On the one hand, it is an important means to guide construction and verify design. On the other hand, it is an important basis to forecast the settlement, adjust the fill plan and determine the time of pavement construction after preloading stabilization. This is also one of the most concerned difficulties in highway engineering research. Monitoring and forecasting the deformation of soft soil foundation is of great theoretical and practical significance. At present, the monitoring data of soft soil foundation are mostly processed by using excel software. Data management is difficult and low degree of information, which is not convenient for the application of practical engineering. At the same time, in the face of a large number of construction monitoring data, the use of traditional methods to deal with more complex, and work efficiency is also very low. Sometimes human factors inevitably lead to data errors. In addition, the analysis of monitoring data results and the use of data are monotonous and fragmented, it is difficult to intelligently and effectively use. Based on these problems. This paper puts forward the establishment of soft foundation monitoring data processing and forecasting system, and applies database to manage and process a large number of field monitoring data, so as to effectively improve the efficiency of soft foundation monitoring. Firstly, this paper introduces the related knowledge of soft soil. Then it introduces the design of the monitoring scheme of the western main road in Dongguan City. Through the analysis of the monitoring data on the spot and the research of the settlement prediction theory. The rule of soft foundation settlement is summarized. The software system is connected with each software and database by Visual Basic6.0 programming language. The soft foundation data processing and forecasting system has friendly interface, simple application, high data processing efficiency, and is convenient for practical engineering application.
