| With the popularity of high-rise buildings in modern construction, the foundationpit shows more features such as becoming larger and deeper, and the security of italso attracts more and more attention. Though there are abundant theoreticalresearches and experiences at present, security accidents still occur from time to time.One of the most important factors that cause accidents is the destruction of thesupporting structure of the foundation pit. So the security of the soldier piles structurebecomes quite important as the soldier piles are the first defense-line of the security.Most of the foundation pits supporting structures attempt to rationalize the securityand the profit by monitoring the changes of the mechanics parameters during theconstruction. When the parameters exceed the setting one, there will be alarm to winmore time for emergency and provide reference to the construction side forsubsequent treatment measures. So the alarm parameter should be scientific andreasonable. A reasonable and scientific alarm parameter can not only prevent theaccidents, but also avoid the construction delay resulting from excessive alarm.This thesis discusses the rationalization of the alarm parameters by stimulatingthe deformation of the supporting plies and anglicizing the results of the monitoring.With mechanical knowledge, analysis the distribution of lateral earth pressuregsupporting pile,and the deformation of the supporting piles by ANSYS;In a supporting pile excavation monitoring, Wuhan City, Select three supportingpiles inclinometer monitoring data analysis supporting piles in foundationconstruction process, observing the changes of horizontal displacement.By analyzing the results of the above work, explore the supporting pileshorizontal displacement monitoring alarm settings are reasonable with the state andrelevant norms of Hubei Province. |
