【摘要】：基坑工程是一种比较普遍的工程类型,随着城市建设的脚步逐渐加快,基坑工程项目也越来越多。因此,基坑工程也逐渐成为社会上众多工程关注的焦点,基于此,基坑工程从设计及到施工,积累的经验也越来越丰富,技术也越来越成熟。本文通过一个具体的工程实践,根据现场实际,因地制宜,基本完整地阐述了基坑工程设计的过程。首先从环境条件、工程地质条件及水文资料等收集的资料出发,深入现场,通过钻探和静探等方法,获得了土质参数。然后根据以往工程经验,对于此类地质情况,对比不同的方案优缺点,选择合适的围护方案,确定设计参数,运用理正深基坑软件进行设计和计算,保证了基坑的稳定安全性要求,并符合相关规范。其次,对工程的监测方案经行了专门设计,参照相关规范要求,及时改善并优化设计方案,确保能够对本工程做到实时监控,采用origin软件对检测数据进行了处理,对本基坑工程的监测数据也经行了分析。因本基坑处于市区,周边有高架,地下有管线,周边环境较复杂,对基坑位移要求较高,经监测得出结论,成功控制了基坑的位移,确保基坑安全稳定。最后,基于本工程概况总结了一些结论和建议,希望对以后的工程有所借鉴意义。
[Abstract]:Foundation pit engineering is a relatively common type of engineering, with the pace of urban construction gradually accelerated, foundation pit engineering projects are becoming more and more. Therefore, foundation pit engineering has gradually become the focus of attention of many projects in the society. Based on this, foundation pit engineering from design to construction, accumulated more and more rich experience, technology is more and more mature. Through a specific engineering practice, according to the site reality, according to local conditions. In this paper, the process of foundation pit engineering design is described. Firstly, starting from the data collected from environmental conditions, engineering geological conditions and hydrological data, it goes deep into the site and through drilling and static exploration methods. Then according to the previous engineering experience, comparing the advantages and disadvantages of different schemes, selecting the appropriate envelope scheme, and determining the design parameters. Lizheng deep foundation pit software design and calculation to ensure the stability of the foundation pit security requirements and comply with the relevant specifications. Secondly, the monitoring project of the project has been specially designed, referring to the requirements of the relevant specifications. Timely improvement and optimization of the design scheme to ensure that the project can achieve real-time monitoring, the use of origin software to process the test data. The monitoring data of the foundation pit are also analyzed. Because the foundation pit is located in the urban area, there are elevated surrounding, underground pipeline, the surrounding environment is more complex, the requirement of foundation pit displacement is high, and the monitoring results are obtained. The displacement of foundation pit is successfully controlled to ensure the safety and stability of foundation pit. Finally, based on the general situation of this project, some conclusions and suggestions are summarized.
