【摘要】：当前我国城市地下空间开发利用的规模越来越大,地下建设工程项目越来越多。随着地下空间开发的深度不断加深,地下建设工程施工难度也越来越大,其中的主要制约因素就是地下水。地下水一方面对地下建设工程施工的安全、质量和进度影响很大,另一方面对地下建设工程周边环境影响也很大。目前在地下工程施工过程中,对地下水控制的主要方法有降水和阻水,也可以两者兼顾使用。但不论采用哪种方法,无疑都会对周边环境产生一定的影响。从大量地下水控制工程的实例总结分析可以看出,其对周边环境的影响有的不甚明显,显现不出危害,有的却是危害非常明显,甚至造成巨大的生命财产损失。因此,在地下水控制工程实施前,如何评价其对周边环境的影响,制定出较合理的应对措施,使地下水控制工程对周边环境的影响减小至最低程度是极其有意义的。本文通过大量地下水控制工程对周边环境影响的实例,对各种影响因素进行了归纳分类,提出采用层次分析法,根据不同环境条件下,各类影响因素的权重不同进行综合评价,在综合评价的基础上选择对周边环境影响较小的地下水控制方法;另外,为了更好地为主要影响因素赋予权重,结合多种计算模型(解析模型和数值模型)对影响进行定量预测;最后,结合多年的实践经验,提出了一些应对地下水控制对周边环境影响的措施,为从事地下水控制工程研究和工程实施的技术人员提供参考。
[Abstract]:At present, the scale of development and utilization of urban underground space in China is becoming larger and larger, and more underground construction projects are being carried out. With the deepening of underground space development, the construction of underground construction is becoming more and more difficult, among which the main constraint factor is groundwater. On the one hand, groundwater has great influence on the safety, quality and progress of underground construction, on the other hand, it has great influence on the surrounding environment of underground construction. At present, in the process of underground engineering construction, the main methods of groundwater control are precipitation and water blocking, which can also be used both. However, no matter which method is adopted, it will undoubtedly have a certain impact on the surrounding environment. From the summarization and analysis of a large number of examples of groundwater control engineering, it can be seen that some of its effects on the surrounding environment are not obvious, and some of them are not obvious, but some are very harmful, and even cause huge loss of life and property. Therefore, before the implementation of groundwater control project, it is of great significance to evaluate its impact on the surrounding environment and formulate more reasonable countermeasures to minimize the impact of groundwater control project on the surrounding environment. Based on a large number of examples of groundwater control projects affecting the surrounding environment, this paper summarizes and classifies various influencing factors, and proposes to adopt the Analytic hierarchy process (AHP) to comprehensively evaluate the influence factors according to the different weights of the various factors under different environmental conditions. On the basis of comprehensive evaluation, a groundwater control method with less impact on the surrounding environment is chosen. In addition, in order to better give weight to the main influencing factors, Combined with a variety of computational models (analytical model and numerical model) to carry out quantitative prediction of the impact. Finally, combined with many years of practical experience, some measures to deal with the impact of groundwater control on the surrounding environment are put forward. For the groundwater control engineering research and engineering implementation of the technical personnel to provide reference.
