摘要
结合龙滩碾压混凝土重力坝的工程实际情况 ,采用广义约束矩阵法研究了该坝典型坝段的温度应力分布及温控安全系数问题 ,给出坝段的最高应力区分布及自重、水压力对温控的影响规律等重要结论 ,为龙滩碾压混凝土重力坝的设计和施工提供了参考依据。
In consideration of real engineering aspect of Longtan RCC dam, the generalized constraint matrix is used to study the temperature stress distribution and temperature control factor of safety in typical dam section. The result gives the max. stress distribution and the regularity of influence on temperature control by self weight and water pressure. It may be used as a reference for design and construction of Longtan RCC dam.
