克孜尔水库2001年2月份的坝面水平位移观测发现主坝桩号0+400～0+750坝段位移量比较大;同时在库区检查发现:主坝桩号0+400～0+750坝段之间坝面有不同程度的纵向裂缝,与历年相比裂缝有所扩大,最大缝宽达到了11mm 左右,发生在桩号0+566.5断面。根据以上异常情况,我们对大坝的坝面水平位移,坝体沉降,坝体水平位移等观测资料做了分析,认为是由于坝顶表面温度伸缩引起的温度缝,心墙没有异常现象。
The horizontal displacements of the dam surface in February 2001 in Kizil Reservoir showed that the displacements of dam sections from 0 + 400 to 0 + 750 of the main dam were relatively large. In the meantime, it was found in the reservoir area that the displacement of the main dam was 0 +400 ~ 0 + There are different degrees of longitudinal cracks on the dam surface between 750 dam sections. Compared with the previous years, the cracks have been enlarged. The maximum gap width reaches about 11 mm, which occurs at the section 0 + 566.5. Based on the above anomalies, we analyzed the observed data such as horizontal displacement of dam surface, settlement of dam body, and horizontal displacement of dam body, which are considered as temperature seams caused by temperature expansion of dam top surface. There is no abnormal phenomenon in the core wall.
