模拟试验

Based on long-term data from operation of a new-style oxidation ditch process at Zhuji Feida-hongyu wastewater treatment plant in Zhejiang Province, we propose a new principle for the interaction of Tubificidae and microorganisms and obtained a mathematical description of pollutant input and output over time in this system. Then a transmission function for interaction system of Tubificidae was constructed to simultaneously simulate the pollutant removal by Tubificidae during wastewater treatment and sludge degradation.

The result notes that dynamic triaxial test preferably simulate the actual stress state of grading macadam, and Uzan model which considers the shear performance of material can better reflect stress states of grading macadam. Regression coefficients of the model obviously present nonlinear characteristic with moisture changed, and to further influence dynamic resilient module.More the module is larger, more diminishing rate of maximum tensile stress on pavement Bottom is smaller. To enhance draining function and strength, the gradation should been rigid controlled, and which the content of less than 0.075mm is controlled between 5～7％ and spring-back is controlled between200~300MPa are appropriate.

结果表明，动三轴试验较好地模拟了级配碎石层的实际受力状态；Uzan模型考虑了材料的剪切性能，更能反映了级配碎石在隧道路面中应力状态；随含水量的变化，Uzan模型中回归系数变化呈明显的非线性特征，进而显著影响级配碎石的动态回弹模量的变化；级配碎石模量越大，路面层底的最大拉应力减小率越小；为了兼顾到级配碎石层的排水渗透功能和强度，应严格控制级配，特别是0.075mm以下的含量宜控制在5％～7％，级配碎石的回弹模量宜控制在200～300MPa之间。
