This research in adopt three-dimensional finite element's pavements structure for analyze mode, inquire into A- 7-5 coherent's roadbeds soil at different water content, will not average bu loading, material nonlinearity, cover earth stress to pavement de affection. This research continue use forefathers already will tyre's model mold draw up become tyre with under pavement's superficial contact stress' condition, again direct to material nonlinearity and cover earth stress under roadbed's soil's different water content's effect, analyze different encourage fetus press with uniaxial's dual wheel load's effect's lower berth's microbus reaction, analyze result emphasize with fatigue failure de adapt to change parameter at groove, depend on order is biggest plumb press adapt to change and biggest level's piece of adaption, difference take place follow depth change and tyre's brim place as depth change under two rings centers, this two kind of adapt to change worth decide pavement's performance, and by yellow xiu wen zhi will research do furthur zhi analysis, compare roadbed's soil moisture content change under pavement zhi affection. At pavement's performance evaluation's aspect, should be used for AI design method zhi groove and tired chap mode theory, direct to section proceed pavement breakage analysis under different water content's effect. By analyze result show, pavement de groove with fatigue failure de severity with loaded car de high fetus press, high axes heavy, water content relevance, so not average bu load with material's nonlinearity mode should compare be able to mold draw up come out real pavement reaction.
