| 摘要: |
| 根据２０多年的观测资料，对漳泽坝的漏测沉降量采用差分法推算，并分析了坝体的变形。坝轴向倾度和水平应变，讨论了坝体出现横向裂缝的可能性。分析表明，在大坝正常应用条件下，坝体出现危险性横向裂缝的可能性不大。目前，坝的运行已进入基本稳定时期。 |

| Abstract: |
| Based on the prototype data of many years for the Zhangze earth dam,this paper suggests a new calculation method for the settlement of observation leak,analysed the possibility of appearance of horizontal fissure at the earth dam top.The analysed results show that settlement of the earth dam is stable and that the dangerous horizontal fissure is not likely to appear under condition of normal use of the earth dam. |
| Key words: difference method,settlement,axis dipping level strain, fissure,earth dam |
