| 摘 要： | 我们利用WSQ-1型自记水管倾斜仪在江苏省徐州市琵琶山山洞（34°20＇N,117°20＇E）对倾斜潮进行了观测.仪器钵体安装在埋入基岩的不锈钢支承棒上,仪器方位为NE117.15°及NE20.50°,格值分别为0.9744ms/mm及0.9429ms/mm.利用维涅第科夫方法对88天（1982年4月至6月）的观测资料进行了调和分析,得到了上述二方位上观测值的主要波群结果.本文还对使用水管倾斜仪进行倾斜潮观测的一些问题进行了讨论.

| Abstract: | WSQ-1 Automatic-Recording Water Tube Tiltmeter was used to observe tilt tides in a tunnel at Pipa Hill in Xuzhou, Jiangsu Province （34°20′N, 117°20′E）. The tilt-meter is installed in NE 117.15° and 20.50° azimuths, and its end reservoirs are set up on stainless steel piers which were placed on the bedrock. The values of scale division of WSQ-1 are 0.9744 ms/mm and 0.9429 ms/mm. Venedikov's method has been used to analyse the observed data for 88 days （April to June 1982）. The preliminary results of the principal wave groups in 117.15°azimuth are given as following:GAMME PHASE LAG SPHGROUP COEFFICIENT SD （deg） （deg）Q1 0.742 0.0690 22.7 5.32O1 0.802 0.0144 10.6 1.03K1 0.744 0.0093 8.76 0.712N2 0.629 0.0566 -3.86 5.14N2 0.660 0.0124 3.53 1.08M2 0.671 0.00257 2.72 0.22S2 0.682 0.0055 -1.16 0.46Some problems about observation of tilt tides using water tube tiltmeter are discussed. |
