摘　　要：以哈达山水利枢纽工程为例，通过填充材料的选取和格室深度及焊距的计算，总结出一种土工格室在寒冷地区应用的范例。通过对试验段和对比段测点冻胀量的观测表明：土工格室蜂窝碎石结构可以有效的削减冻胀量，具有很好的适应冻融变形能力。而且土工格室护坡结构具有很好的经济效益和生态效益，具有推广价值。Taking the Hadashan hydro junction project as an example, applied example of geocell in cold area was summarized through the selec- tion of the filled materials and the calculation of depth and welding distance of the geocell. Through observing the test section and contrasted section,the frost heaving of them shows that the geocell gravel structure could effectively reduce the frost heaving quantity and well adapt the freezing and thawing de- formatior~ And geocell slope protection structure had good economic benefit and ecological benefit,which was worth promoting.
