Until today, HydroResearch and Sensornet have installed optical fibres for monitoring of seepage and/or movements in more than 20 dams, dykes and tailing dams at 16 different dam sites in Sweden.
Challenges of high dam construction to computational mechanics
例句来源
Dam-foundation interaction plays an important role in the design of earthquake-resistant concrete arch and gravity dams.
例句来源
Geological conditions of the dam canyon are usually very complicated; however, in the literature, the damfoundation interaction analysis is often carried out based on the premise of a homogeneous unbounded foundation.
例句来源
It was found that a homogeneous idealization of the unbounded foundation may sometimes greatly underestimate the maximum earthquake stress response of the dam.

Three-dimensional stability analysis of the dam foundation at Baise
This article presents a method for calculating the gravity dam with various types of opennings.The procedure takes as follows: First step:Assuming the dam as a solid body,calculating it's stresses. Second step:Along the boundary of the opennings,applying forces which equal but opposite to the primary,and assuming the openning is placed at an infinite region,we obtain the stresses weakened by openning. Third step:Combining these stresses,the final stresses in dam are given. If the openning ...
This paper discusses some problems which are found to be important in designing the arch dam of the Liv-Hsi-Ho-hydroelectrical power station. The arch dam under discussion has a max. height of 82 m and spans 255. m, situated in a V-shaped valley. It is an overflow arch dam of the various radius and thickness type. The technical design has been nearly finished and the dam is now under construction. The first problem discussed is the investigation of the stability of arch dam un...
In this Paper,the important problems of temperature stresses in arch dams are analyzed. Firstly,we consider the transient elastic three dimensional temperature stresses.It is pro- posed to cut the dam into horizontal and vertical systems,compute the stresses and dis- placements arisen therein by the nonlinear temperature distribution on the assumption of Plane section of Bernoulli-Navier,then adjust the displacements of the horizontal and ve- rtical systems by the so called trial load method.Som...
