Examples
- Because the observation of interior crack is not always available , this paper laid emphasis on surface crack of segments
由于管片内部裂缝观测难以实现，故重点研究了表面裂缝的影响。 - Here aiming at temperature and traffic load factors , have a systemic study about strcture ' s stress distribution . plan is to make use of ansys to calculate pavement structure ' s distortion with full grade gravelly interlayer carefully through changing each layer ' s thickness and module . next , analysize stress among bottom of surface asphalt layer and top of semi - rigitidy base . lastly . make a conclusion : how to distrube stress and strain about the structure after adding gravelly interlayer
方法是采用ansys对加设级配碎石基层半刚路面结构进行多种参数模拟计算，通过改变结构材料厚度、模量等观察基层和面层应力变化，研究碎石基层怎样调整结构应力而防止了温度和行车荷载产生的过大拉应力，避免基层产生内部裂缝。
