The optimized pattern of this kind of green spaces is : the layer of arbors has the coverage higher than 80 % with species grow fast and has strong resistance against air pollutions. the layer of shrubs has the coverage around 50 - 60 %, giving property to evergreen species, sprinkled with flower shrubs to enrich the aesthetic benefits. ( 3 ) tall arbori - small arbor + shrub pattern has the best ecological benefits among the four typical configuration patterns of the gardens in tindustrial district with the evaluation result of 0. 8520 while lawn pattern at the latest with the result of 0. 4014 ; tall arbor + small arbor + shrub pattern has the best aesthetic benefits with the result of 0. 9620 while lawn pattern at the latest with the result of 0. 7071 ; shrub + lawn pattern has the lowest investment of construction and maintenan

In the end, the steel - reinforced concrete arched bridge ( chun ' an weiping bridge ), which span is 198m, is analyzed by the proposed three - dimensional nonlinear finite element method and also those gained conclusions are directly adopted in the computation. the universal stability coefficient and nonlinear buckling stability coefficient of the bridge are respectively computed, in which the dead load and the live load are assembled according to the criterion. on the other side, the regularities of creep deformation and subsidiary stress of the investigated bridge under the first - stage dead load are carefully researched
