摘　　要：高寒地区水工建筑物基础采用EPS板来保温,抵御因地基冻胀而引起的破坏,已取得了明显的效果。采用野外现场模拟,对EPS保温基础进行了四个冬春的观测,取得了现场实测资料及成果。通过对不同密度、厚度的EPS保温基础的温度场变化规律的分析研究,验证了EPS基础保温工法可抑制冻胀的可行性,为进一步完善EPS板的防冻理论和实用经验提供了参考依据。It has gained the obvious effectiveness that applying the EPS heat insulating boards to the foundation of hydraulic structures can resist the frost heave damage of the foundation, the EPS heat insulating foundation is observed for four winters and springs and the temperature field of the foundation is analyzed by in-situ simulating in the field,and the observation data are obtained. The test result validates the feasibility that the EPS heat insulating foundation method can reduce the frost heave from the analysis of temperature field changing laws with different density and different thickness of the EPS heat insulation foundation. It can offer referring gist for consummating the anti-frozen theory and practical experiences.
