| 摘 要： | 1983年至1985年楚雄水管倾斜仪观测表明:楚雄地区的地壳表层是向东南方向倾斜的,与云南西部的红河断裂和哀牢山褶皱带的走向是一致的;楚雄台的台基是不均匀的,它表现在观测结果受外界干扰大和潮汐分析结果有方向性;地表观测与山洞(覆盖约30米)内观测的结果不能很好地符合,它表现在地表观测的倾斜方向规律性不好和干扰大于山洞内的观测。

| Abstract: | The observational data of the water-tube tiltmeter at Chuxiong from 1983 to 1985 show that the crustal surface layer in the Chuxiong area tills to the southeast, which is coincident with the strike of the Red River fault and with that of the folded belt of Ailao mountain chain in the western Yunnan. And the bed rock of the site of Chuxiong Station is not uniform, which is indicated by the fact that the observational results have been greatly influenced by external factors, and the result of tidal analysis has a certain direction. The surface observation and cave observation ( overburden layer is about 30M ) do not perpectly accord with each other. It shows that the regularity of tilt direction on surface observation looks poor and the interference on surface is greater than that in cave. |
