In recent years, with the development of China 's transport undertakings - span continuous rigid frame bridge as a large - span bridge type , span a wide range of applications in the field of bridge engineering , especially in the high mountains and hydropower reservoir area pier continuous rigid frame bridge is in the majority. However , in the high pier span continuous rigid frame bridge construction subject to many uncertainties interference , which makes the structure of the internal forces and deformation continuously changes , effective monitoring of the construction must be carried out in the construction process , in accordance with the design to ensure that the internal forces and linear requirements. This article expansive Kaito Bridge engineering background of high - pier long-span continuous rigid frame bridge construction linear control technology research and exploration . The main work : 1) introduces the continuous rigid frame bridge development history , current situation and development trend of the construction control role in the construction of bridges and significance . 2 ) describe the prestressed concrete continuous rigid frame bridge cantilever construction of the basic principles of control theory , technology and methods , as well as construction control the specific content focusing on analysis of the impact of continuous rigid frame girder bridge construction control of the main factors . 3) The expansive Kaito Bridge engineering background , and bridge structural finite element analysis software the Midas-civi12010 establish finite element simulation analysis model , analyze concrete bulk density , elastic modulus , environmental temperature and humidity , creep parameter sensitivity of continuous rigid frame bridge construction control . 4 ) calculation and analysis on the effects of shrinkage and creep factors , and to explore how to quickly determine the actual construction monitoring creep coefficient in order to better service for the bridge construction .
