Monitoring Of Deep Foundation Pit Excavation Construction Management Research

Since the 21 st century,the rapid development of China's national economy at an alarming rate,with the influx of a large number of rural population,domestic also in urbanization advancement speeding up unceasingly,to accommodate more people and to build a city landmarks,cities of the high-rise buildings have sprung up.But how to take appropriate means of construction monitoring in the construction,to guide the construction work,is the concern for academic circle,this article through to gansu xinhua bookstore group co.,LTD.New HuaYi garden economy applicable room community building construction of deep foundation pit excavation engineering as an example,the construction monitoring of the collected data are analyzed,and combined with the data on the scene of the engineering construction and design to make the instruction,the monitoring data in engineering is discussed.This paper mainly studies the supporting structure of deep foundation pit engineering problems related to the construction monitoring and combed the theoretically support technology for deep foundation pit engineering theory study,at the same time as the background on the project example,analyses the construction monitoring data in the practical engineering application,and analyzes its causes,and subsequent processing method,finally obtained the related conclusion view:(1)the construction monitoring of deep foundation pit engineering is important,it not only can alert the danger in construction,can also through the accumulation of basic monitoring data,monitoring project lays the foundation for later,finally the construction monitoring data can also improve and supplement to design work.(2)the displacement of supporting structure in deep foundation pit engineering,and the excavation depth and speed of correlation,if the excavation speed too fast,is likely to happen,at the same time must adhere to stratified excavation,not covet shortcut,lose control of the excavation depth.(3)the maximum displacement of deep foundation pit engineering of soil nailing structure generally appear at the top,and the horizontal displacement values,will decrease with the increase of depth,(4)the deformation of deep foundation pit supporting structure is associated with many factors in the construction,and the factors affecting water is serious,two of the measuring point displacement mutation in terms of these engineering because of the influx of foreign water crisis occurs,therefore should prepare relevant drainage measures in the foundation pit excavation.(5)when the soil condition is not ideal,can take powder spraying pile strengthening of soil nailing structure reinforcement in the form of using the monitoring data proved ideal effect.(6)because of the complexity of the deep foundation pit engineering,so it is recommended to use mathematical model of neural network as a foundation for the construction monitoring data in the future.
