Abstract Research purposes : This paper analyzes the reasons and characteristics of the main structure transmutation of underground engineering in construction and circulation, summarizes the transmutation principle and forecasts the development trend of transmutation. Therefore, it is necessary to observe the primary structure transmutation, master the circs of structural transmutation dynamic, adopt proper remediation steps on the larger transmutation region in times, insure the circulating security.
Research conclusions: When urban rail transit engineering begins operating, the primary structure may occur transmutation generally. So, it is necessary to adopt some proper means to observe and it is necessary to master the structural transmutation status in time. These are of advantage to operating safely and these should be much accounted of by correlative departments.
