黄河水利委员会头道拐水文站断面右岸,因受地形限制,基本水准点设在高崖上,引测水准点零点高程费时费力。为引测方便,在崖下近水边处设校核水准点,但因受冻土层膨胀影响容易上拔。设站以来十多年内,水准点高程经常发生变动,水文资料质量受到一定的影响,也给资料整编工作带来很多麻烦,是一项迫切需要解决的问题。为了妥善解决这个问题,站上先采用加大水准点底座混凝土尺寸和重量的方法,但未获彻底解决。后改用在水准点钢管外加钢套管,两管间填黄油的方 The Yellow River Water Conservancy Commission on the right bank of the first section of hydrological station hydrological station, due to terrain constraints, the basic level of the point set in the high cliffs, cited the standard point zero elevation time-consuming and laborious. For the convenience of the cited test, a check point is set at the cliff near the water, but it is easy to pull up due to the expansion of the frozen soil. Since the establishment of the station more than a decade, the standard point elevation often changes, the quality of hydrological data is affected to a certain extent, but also to the data reorganization work a lot of trouble, is an urgent problem to be solved. In order to properly solve this problem, we first adopted the method of increasing the size and weight of concrete at the level of the base, but it was not completely solved. After the switch to the standard steel pipe plus steel casing, two sides filled with butter
