Method for determining automobile wheelbases to conduct load analysis

The invention belongs to the technical field of bridge structure computational analysis and discloses a method for determining automobile wheelbases to conduct load analysis. By the aid of the method, determined wheelbase values are matched with the situation of actually-running automobiles and are scientific, and accurate wheelbase data are provided for research of influence of automobile loads on bridges. The method comprises the steps of firstly, surveying types of automobiles passing through the bridge to be researched, and determining vehicle types to be analyzed according to vehicle type classifications and influence degrees of vehicle types on the bridge; then conducting data surveys of automobile wheelbases according to vehicle types, and enabling wheelbases to serve as random variables; and obtaining automobile axle loads through surveys, obtaining a 'load calculation chart' of automobiles according to wheelbases and corresponding axle loads, and conducting bridge and automobile load analysis.
