Analysis in Stability of Monitoring Network for Deep Foundation Pit Based on Mean Spacing Method

Abstract:

Based on establishing monitoring network in accordance with the requirements of criterion, monitoring network for deep foundation pit in the people's hospital of jilin province has been taken as research object to collect multi-period network information. Based on free net adjustment method, the combined adjustment has been carried out in multi-period plane network. Choosing displacement variation of two control points as mean spacing in plane network, and using mean spacing method program in MATLAB platform to calculate sample and population variance of observed value, structure F distribution and analyze the stability of monitoring points. The results show that using mean spacing method can rapidly distinguish the stability of monitoring network and points, which offers reliable gist for monitoring project.
