By using the constitutive model , we can establish the creep and consolidation model , the variation trend of super pore water pressure and the development of viscoelastic settlement and viscoplastic settlement . at last forecasting the long term creep settlement in the metallurgy industrial estate at the backward position of haihe river in tianjin 并利用此本构关系建立蠕变与固结模型，计算出土层在大面积填土作用下超静水压力发展趋势，同时得出其粘弹性、粘塑性沉降发展趋势，最后对冶金工业区软土长期蠕变沉降作出预测。
About the load , consider the vertical load , when under the action of water , consider the horizontal still water press , the press which erects to the surface of slide , and consider the effect of hydrodynamic load and earthquake . ( 3 ) the software about the frame design , apply the stiffening bar method and elastic foundation method to account the endogen 对于荷载(或工况) ，考虑了外加垂直荷载；在有水作用的情况下，考虑了水平静水压力，垂直滑面的静水压力(也叫浮托力) ；考虑动水压力的影响；同时也考虑了地震的影响。
This paper establishes a model simulating dam actual placing process and considering the non - continuity of initial temperature on the boundary of new and old concrete , daily air temperature change , concrete - placing temperature , hydration heat , heat insulation on boundary , water - storing process , placing intermission and curing with water . the calculation of stress field considers the concrete weight , static water pressure , thermal stress , different autogenous volume change between rcc and normal concrete , change of elastic modulus of concrete with age and creep action 考虑了乞今最为全面的初始条件和边界条件，包括模拟坝体的实际升程过程，考虑了新老混凝土接触面上的初始温度不连续，逐日的气温变化，混凝土的入仓温度，水化热温升，边界保温，水库蓄水过程，浇筑间歇以及洒水养生等因素；应力场的计算考虑了混凝土的自重，静水压力，温度应力，常态混凝土与碾压混凝土不同的自生体积变形，混凝土的弹性模量随龄期的变化以及徐变的作用。
