Application Research On Comprehensive Evaluation Method Of Bridge Bearing Capacity

In the past twenty years,the rapid development of highway transportation infrastructure in our country,a large number of highway Bridges have been built and played an important supporting role in the transportation.However,due to the vehicle,especially in the overweight vehicles,as well as a variety of internal and external factors,the effect of highway Bridges in use will produce all kinds of diseases and defects after so many years,its carrying capacity is reduced,thus affecting its normal use.Therefore,how to assess the actual bearing capacity and plant disease development of these Bridges,in its maintenance and highway management work is very important.In the existing economic and technical conditions,how to accurately assess bridge carrying capacity is a hotspot of current research problems.The specific contents and conclusions of this paper are as follows:1.Main parameters affecting the bearing capacity of bridge structure is analyzed,and according to the existing bridge detection technology and bridge bearing capacity evaluation method,inductive bridge carrying capacity comprehensive evaluation method of technical route and the specific work content.2.In the practical engineering use,through the actual traffic investigation,traffic flow and vehicle load conditions of the bridge bearing capacity checking evaluation results,the influence of the other,using the engineering example of the existing bridge health monitoring system,environment temperature and sunshine of the bridge condition effect on stress,improve the precision of bridge bearing capacity evaluation.3.Combined with practical engineering projects,use of bridge carrying capacity comprehensive evaluation technology route testing evaluation of both the bearing capacity of the bridge,as a bridge bearing capacity checking evaluation of practical engineering use play a demonstration role.
