摘　　要：叙述了水管式沉降仪的原理和结构,分析了目前使用中存在的一些问题,如水管式沉降仪测量时给管路充水容易、排水困难、水管沉降仪管路埋设时通常采用的整体坡降法对于施工影响较大等。结合在实际安装和使用过程中的经验、教训,并经过实验室和工程实际的运用,最后提出了水管沉降仪的结构及埋设方法的几点改进意见,如采用双排水系统解决系统排水难的问题、采用局部坡降法埋设解决整体坡降法埋设对施工干扰大的问题。The principles and structure of hydraulic overflow settlement gauge are described.The existing problems during its application are analyzed.For example,the pipeline is easily filled with water,but its drainage is very difficult.The commonly used overall gradient method for installing the hydraulic overflow settlement gauge has great impact on the construction.Based on the experience and lessons from the actual installation of the gauge both in laboratories and projects,several suggestions for improving its structure and installing methods,such as use of the dual drainage system to solve the problem of difficult drainage and employment of the local gradient method to solve the problem of great impact on the construction by use of the overall gradient method.
