摘要

为研究锚固在刚性基座侧壁上的充气橡胶坝的横截面构造和拉力,进行了一项理论研究。使用横截面周长为 1.0 米、长度为 8.5 米的橡胶坝模型进行了一系列大型模型试验。研究发现,橡胶坝有一个最佳高度,特别是随着充气气压的增加,锚固深度越大。锚固深度越小,最佳充气压力越高。橡胶坝与刚性基座之间的接触长度随着充气压力的增加而逐渐减少。锚固深度越大,接触长度减小到零的速度越快。一般来说,拉伸力随着归一化气压的增加和锚固深度的减小而线性增加。

Theoretical and experimental studies on air-inflated rubber dam anchored on sidewall of the rigid base

A theoretical study was conducted to investigate the cross-sectional configurations and the tensile forces of an air-inflated rubber dam anchored on the sidewall of the rigid base. A series of large-scale model tests were conducted using rubber dam models with a cross-sectional perimeter of 1.0 m and a length of 8.5 m. The results obtained from the analytical solutions agree well with those obtained from model tests. It is found that there is an optimum height of the rubber dam, especially for larger anchor depth with the increase of the inflated air pressure. The smaller the anchoring depth the higher the optimum inflated air pressure. The contact length between the rubber dam and the rigid base gradually decreases with the increasing inflated air pressure. The greater the anchor depth, the faster the contact length decreases to zero. Generally, the tensile force linearly increases with the increase of the normalized air pressure and the decrease of the anchor depth.

期刊介绍: The range of products and their applications has expanded rapidly over the last decade with geotextiles and geomembranes being specified world wide. This rapid growth is paralleled by a virtual explosion of technology. Current reference books and even manufacturers' sponsored publications tend to date very quickly and the need for a vehicle to bring together and discuss the growing body of technology now available has become evident. Geotextiles and Geomembranes fills this need and provides a forum for the dissemination of information amongst research workers, designers, users and manufacturers. By providing a growing fund of information the journal increases general awareness, prompts further research and assists in the establishment of international codes and regulations.
