摘　　要：胶凝砂砾石坝作为一种新坝型,具有安全性高、经济环保、施工快速等优点,但仍有诸多问题需要解决,尤其要推广应用到高坝工程中。本文根据胶凝砂砾石坝的材料特性和施工工艺,提出简化其施工温控措施的设想,以一座百米级胶凝砂砾石坝为例,采用三维有限元法对其简化温控措施前后的温度场和应力场进行仿真分析,仿真分析计算结果为胶凝砂砾石坝简化温控措施、加快施工速度提供了依据。Cemented sand and gravel（CSG） dam is a new type of dam. Although it has the advantages such as high safety, eco- nomic and environment-friendly, quick construction, etc. , so many problems are there necessary to be solved for it, especially when it is popularized to the construction of high dam. By taking a CSG dam with the height of 100m as the study case, an as- sumption for simplifying the temperature control measures for the construction of CSG dam is proposed herein in accordance with its material properties and construction technologies, and then a simulation analysis is made on the temperature field and stress field before and after simplifying the temperature control measures with the 3 - D finite-element method. The calculation result of the simulation analysis can lay a basis for simplifying the temperature control measures and accelerating construction speed for the construction of CSG dam.
