Loess Areas Of Highway Foundation Bearing Capacity Evaluation Method And Regional Studies

Ground bearing capacity is one of the important factors that influence the structural stability of road base. Reasonably to determine the ground bearing capacity in loess area is a vital problem to be solved in road construction. This paper exploits the determining way for the values of ground bearing capacity through analyzing the data of actual examination on load. From the aspects of quantity, nature and macro-angle, we analyze the influencing factors and regulations of change in the ground bearing capacity and divide the areas of different loess. This paper proposes regressing formulas for correspondent physical force indexes and synthetic evaluation of fuzzy mathematics to determine the ground bearing capacity. At last, according to the actual examples, this paper projects the practical methods to determine the ground bearing capacity in loess area. The results of this paper has great significance in determining the ground bearing capacity of road base and has reference value for the design of the road base.
