摘　　要：基于材料费用管理量价分离原则,分别识别影响盾构管片费用的量和价的因素,利用系统动力学原理,绘制因果关系图。然后根据实际情况,结合因果关系图构建系统流图及部分模型方程。最后以某盾构施工地铁项目为例,完善模型方程,并分析各因素对管片费用的影响程度和影响规律。Based on the principle of quantity and price separation of materials costs management,this paper identifies the factors that affect the quantity and price of shield segment respectively,draws the causality diagram based on the principle of system dynamics.Then,constructs the system flow chart and some model equations according to the actual situation and causality diagram.Finally,taking a shield construction subway project as an example,analyzes the influence degree and the influence rule of various factors on segment costs.
