| The reform and opening up has brought China’s urban construction peak, high-rise building construction, construction of large municipal facilities and a large number of underground space development, there must be a lot of the foundation pit in order to meet the structural requirements of the tall buildings and wind must also be requirements for deep foundation pit excavation. Excavation monitoring deep foundation construction process, a comprehensive system of foundation pit supporting structure, excavation around the soil and adjacent structures is understood that the excavation works in a safe, steady state, to ensure thatworks smoothly."Building foundation pit monitoring technical specifications"(GB50497-2009) building Foundation project monitoring made more systematic and comprehensive regulations. But in the real construction process, the specific method of operation is not detailed enough and needs further study. This paper studies the content of the following areas:1."Building foundation pit monitoring technical specifications" part of the standard, to make regulatory requirements more easily understood and the exact reference for the actual construction.2. Foundation pit engineering measurement method of horizontal displacement monitoring, building subsidence monitoring, and deep horizontal displacement monitoring has been studied on deformation measurement.3. Foundation pit engineering measurement method of enclosure system internal force monitoring, soil pressure monitoring has been studied on internal force monitoring.4. Combined with Ji’nan a large foundation pit monitoring data, further study of the horizontal displacement monitoring, building subsidence monitoring, retaining structure internal force monitoring, soil pressure monitoring and surveillance methods in the application of practical engineering. 5. In the paper is summarized on the basis of the research work, on the subject of follow-up research prospect. |
