Hoshino algorithm is improved based on the basic idea of three point method , and model of Three Point-Hoshino algorithm is established . The feature of Three Point-Hoshino algorithm i analyzed and then the scope of it reasonable collocation i discu ed . Combining with measured data collected in highway subgrade filled by construction waste in North Loop from Xi5an to Xian Yang , three point , expanded hyperbolic method , Hoshino algorithm and three point-Hoshino algorithm were
