一、前言近来,特别是随着电力工业中抽水蓄能发电的飞速发展,土坝的规模日趋大型化。坝高在100米以上的大坝业已相继规划、兴建。无疑,这反映了在坝工技术、尤其是筑坝材料性质的掌握和引进大型施工机械等方面的不断的显著进步。但是,另一方面,土坝的设计方法和计算理论仍然停留在摸索经验和累积资料阶段,尚未建立一套作为土工建筑物所必要的设计方法,因而不可否认地在设计分析中尚存在相当的盲目性。现在所 I. Preface Recently, with the rapid development of pumped storage power generation in the power industry, the size of earth dams has become increasingly large. Dam height of 100 meters above the dam have been planning, construction. This undoubtedly reflects the continuous and significant progress made in the technology of dams, especially in the control of the nature of dams and in the introduction of large-scale construction machines. However, on the other hand, the design method and calculation theory of earth dam remain at the stage of groping experience and accumulating data, and have not yet established a set of design methods necessary as geotechnical buildings. Therefore, it is undeniable that there is a considerable blindness. Now
