Based on the segmental joint tests, it was found that the practical range of joint flexural rigidity was in range of 8500-29000kN•m/rad. A simplified method for determining the stiffness reduction factor of tunnel lining() was proposed using results from the segmental joint tests in which some parameters were obtained by calibration against a 3D Numerical analysis. The influence of joint flexural rigidity, soil resistance coefficient, thickness of tunnel lining and tunnel calculation radius on the stiffness reduction factor of tunnel lining was examined. The stiffness reduction factor can be simply expressed as a function of joint flexural rigidity ratio, soil resistance coefficient, thickness of tunnel lining and tunnel calculation radius for the typical tunnel lining.

Slot bottom size has directly effect on conductor abrasion,Chinese Technical Regulation of design for Stringing blocks of overhead transmission lines (DL/T371-2010) clearly states that slot bottom size should be no less than 20 times of the size of conductor to be extended. In this paper, based on effect of slot bottom size on conductor abrasion,the size of slot bottom of stringing pulley is analyzed. Some useful suggestions are given.

To study conductor damage induced by different patterns of string pulley in process of tension stringing, damage experiment is performed on string pulleys with multi wheels and single wheel. Damages occurred on conductor by two different kinds of string pulleys are analyzed. Results show that there are no significant decrements in strength of conductor with trapezoidal conductor when it is passing through different patterns of string pulley. It indicates that damages on conductor with trapezoidal conductor caused by both types of string pulley are similar. It is also found that average strength of conductor with circular conductor decreases 1.60% and 2.99% when conductor is passing through string pulley with single wheel and multi wheels over twenty times. It is concluded that strength damage on conductor with circular conductor induced by multi wheels is a little larger than that by single wheel

It is critical to understand the workload characteristics and resource usage patterns of available applications to guide the design and development of architecture of the future large scale servers. In this paper, we analyze the workload performance characteristics of the actual Bank Intermediary Business (BIB) characteristics with BIBmodel and BIBbench design work, and propose BIB performance workload and use case definitions. The analysis and comparisons of workload and use case illustrate that the workload performance characteristics of BIB is totally different with TPC benchmarks. With the development of economy and technology, the requirements for BIB servers are important in modeling, benchmarks developing and workload performance characteristics studying are increased nowadays.
