Activity handover within engineering construction projects is time consuming, takes longer than the actual activities, and therefore, can cause duration delays. This paper presents relay chain seamless handover (RCSH) technology, which is based on relay technology theory and actor-network theory. This study systematically elaborated the RCSH processes, activity relay flows, and methods to addre...

Firstly, the concept of digital reservoir is proposed and discussed in the paper, then the method how to monitor dam’s state by digital means and how to transmit the monitoring data by GPRS technology is presented, and the method can monitor the dam’s state in real time and its advantages such as real-time, visibility, visualization are analyzed later. The indicators reflecting the safety of da...

The static stability evaluation of tailing dam is one of the most important tasks in the mine environmental protection project. The methods for the static stability calculation were discussed in this paper, which were Swedish Circle Method, Janbu Method, Bishop Method, Finite Element Method and Strength Reduction Finite Element Method (SRFEM) with five different failure criterions considered. T...

Efficient mode shape extraction of fluid-structure systems is of particular interest in engineering. An efficient modified version of unsymmetric Lanczos method is proposed in this paper. The original unsymmetric Lanczos method was applied to general form of unsymmetric matrices, while the proposed method is developed particularly for the fluid-structure matrices. The method provides us with si...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

Eight successively refined simulation models for the earthmoving operations involved in the construction of a dam provide the foundation for illustrating the ease and effectiveness of modeling complex construction processes by using STROBOSCOPE, a modern simulation system based on a programming language that follows the activity-scanning paradigm. This approach and the use of characterized reso...

Agricultural droughts are droughts that affect the crop production or the ecology of a region. Ravar city that is located in margin of desert and the north of Kerman province is one of these areas. Due to the existence of enough underground water that entrance to desert and high evaporation to improving agricultural and cultivar activities, it needed to study the construction of underground dam...
