摘　　要：陡坡坝段由于约束区较长,一般而言,基础部位的温度应力较之其他坝段要大,因此温度控制应更为严格。本文选用多坝段联合作用模型,研究了不同封拱方式对大坝温度场、应力场及稳定状态的影响,旨在为施工期动态设计提供决策支持。The temperature stress of the basic parts of steep slope sections is higher than other dam sections generally due to relatively long confined region. Therefore,the temperature is controlled more strictly. Multi-dam joint action model is selected in the paper for studying the influence of different arching modes on dam temperature field,stress field and stability state,thereby aiming at providing decision-making support for dynamic design in the construction period.
