适用范围

The Manual has been divided into eight Sections@ with each Section representing a distinct phase of an overall bridge inspection and evaluation program. ? Section 1??Purpose@ scope@ applicability@ inspection and evaluation quality measures@ and definition of general interest terms. ? Section 2??Provisions for proper documentation to be included in a bridge file. The bridge file associated with each bridge provides the foundation against which changes in physical condition can be compared. ? Section 3??Overview of bridge management systems and their key elements. ? Section 4??Types and frequency of field inspections@ as well as specific inspection techniques and procedures. ? Section 5??Various inspection and evaluation testing methods. Conditions at a bridge site or the absence of information from original construction may warrant more elaborate material tests to determine properties for evaluation. ? Section 6??Nationally recognized specification for the load rating of bridges. Includes the Load and Resistance Factor method@ the Load Factor method@ and the Allowable Stress method. ? Section 7??Provisions for the evaluation of existing bridges for fatigue. ? Section 8??Field-performed load test procedures. Field load testing is a means of supplementing analytical procedures in determining the live-load capacity of a bridge and for improving the confidence in the assumptions. The successful application of this Manual is directly related to the DOT organizational structure. Such a structure should be both effective and responsive so that the unique characteristics and special problems of individual bridges are considered in developing an appropriate inspection plan and load capacity determination.
