In recent years , with the improvement of national income and the reduction of urban land to meet the sound and rapid development of economic construction requirements, many large, very large civil engineering projects have emerged, such as the Qinghai-Tibet Railway , the Olympic project , the South , the city subway and so on . These large construction projects by the world's attention . In this paper, these high , large, heavy, deep foundation design and construction in support scheme selection difficult conditions, the article by an industrial park deep excavation process monitoring, describes the following: a ) describes the deep excavation and research the historical background of the development of the status quo. 2 ) describes the prestressed anchor piles calculation method . 3 ) through on-site monitoring, on deep foundation construction technology and information feedback system briefly made ??a presentation to explain the excavation process, by the surrounding environment, climate conditions , engineering geology, construction conditions, the impact of space-time effects, etc. will focus on analyzing the soil nail wall and the pile anchor system deformation mechanism , play a timely forecasting dangerous situation during the construction pit effect , thus proactive take emergency measures to avoid accidents. Also verified the foundation pit design for the future design and construction has accumulated valuable experience . 4 ) combined with text , pointing out that the construction of information technology is a means of deep foundation is essential , is the center of the process . This combination , it is deep excavation in the future studies should be concerned about the prospect to do to a certain extent .
