| 摘 要： | 考察了山西峨嵋台地万荣城区一带的挤压型地裂,发现其呈北西-南东的条带状,1985年发生,至今仍在发展。地裂带上墙砖、水泥地砖拱曲翘起,水泥地面条带状拱曲,土体发育呈波浪条带状垅岗;墙体开裂,墙体裂缝中间宽上下两头细,地裂带上X型破裂发育。分析了万荣城区一带地裂的特征,讨论了万荣挤压型地裂的力学成因机制。

| Abstract: | Compressive terra cracks in urban Wanrong county,belonging to Emei platform of Shanxi province,is investigated.It is found that these compressive terra cracks strike along northwest-southeast,being in belt shape,generated in 1985 and still developing as yet.Wall bricks and concrete floor bricks over the terra cracks are arched and warped,concrete ground is arched in belt shape and soil develops into wave bar-shape ridge hillock.Wall cracks are usually wide in middle and thin on both up and down sides.X cracks are developmental in the terra crack belt.Characteristic of terra crack in urban Wanrong county is analyzed and mechanical mechanism of compressive terra crack in Wanrong is discussed. |
