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.

In this research uses the three dimensional limited element store front structure is the analysis pattern, discusses the A-7-5 condensation roadbed soil in the different water content, the non- uniform load, the material non-linearity, turns the soil the stress to the store front influence. This research continues with the predecessor has simulated the tire model the tire and under the store front surface contact stress condition, again aims at the material non-linearity as well as turns the soil the stress under the roadbed soil different water content function, the analysis differently hits the tire to press with the single axle double round application of load under the store front response, the analysis result emphatically in the wheel rut and the weary destruction strain parameter, in order open the strain for the most greatly vertical pressure strain with the maximum level, separately occurs under two turns of centers along with the depth change and the tire edge along with the depth change, this two kind of strains value decided the store front achievements, and make further the analysis research by Huang?wen, Compared with roadbed soil moisture content change under influence store front. In the store front achievements appraisal aspect, applies wheel rut of and the weary chap pattern theory to the AI design method, the cross section carries on the store front destruction analysis in view of the different water content function under. Demonstrated by the analysis result, store front wheel rut and weary destruction gravity and car or machine with load Gao T'aiya, Gao Chouzhong, water content related, therefore the non- balanced load and the material non-linear pattern should comparatively be able to simulate the real store front response.Source(s): 自己
