Scour Technology

Description

Structures built in or near rivers and other channels can be vulnerable to scour around their foundations. If the depth of the scour becomes significant, the stability of the foundations may be endangered, with a consequent risk of damage or failure of the structure. There have been several bridge failures, resulting in transport disruption, economic loss and, on occasion, loss of life. The factors influencing scour are complex and vary according to the type of structure. Protection for preventing scour needs to be designed to withstand the flow forces imposed on them and have to be practical to build and install, while minimizing adverse environmental effects. This book covers the entire Scour Technology area and is prepared by one of the leading experts on the subject.

描述

在河流和其他水道附近建造的結構可能會受到其基礎周圍的沖刷的威脅。如果沖刷的深度變得顯著，基礎的穩定性可能會受到威脅，進而導致結構的損壞或失敗的風險。已經發生過幾起橋樑失敗的事件，導致交通中斷、經濟損失，並且有時還造成生命損失。影響沖刷的因素復雜且因結構類型而異。預防沖刷的保護措施需要設計成能夠承受施加在其上的流動力，並且必須在建造和安裝時具有實用性，同時最大程度地減少對環境的不良影響。本書涵蓋了整個沖刷技術領域，並由該領域的領先專家之一編寫。
