Faced with serious tensile–shear fracturing of anchor bolts and cables in deep roadways, it is great significance to investigate Anchor Cable C-shaped tube (ACC), a combined structure an cable high strength shear resistance. The mechanical properties the ACC are systematically investigated using technical means theoretical analysis double-shear tests. improved equipment for test not only consid...

The penetration of ship anchor, which is a very important factor considered in the design stage subsea cable burial, highly dependent on geometrical specifications and shapes anchor chain. In order to facilitate predicting depth by an arbitrary ship, formulations correlation between mass existing chain were attempted. particular, for small ships with equipment number 40 (corresponding DWT 90) o...

Anchor cables often break in various forms. Tensile failure can be resisted by using high-strength materials, while there is no good solution for shear failure. A new supporting structure called Cable and C-shaped tube that bear the transverse force was invented a preliminary introduction to mechanism of given. Field investigations in-situ stress tests were carried out on panel 3210 Nanguan Min...

The research on the anchoring mechanism of slope anchor cable under earthquake action is not in-depth. Therefore, it has become an urgent problem in engineering practice to study seismic characteristics system and then realize optimal design anchoring. In this paper, dynamic response a rock strengthened with full-length bonded studied by centrifuge model test. It found that internal structure i...

Carbon Fiber Reinforced Polymer (CFRP) has advantageous characteristics such as lightweight, high strength, corrosion and fatigue resistance, low creep, damping, etc. It is suitable to be used in bridge structures cables, which can effectively solve the problems of easy rusting, heavyweight, tensile performance steel cables. This paper firstly illustrates properties CFRP lamella compared with r...

For the quick and accurate determination of cable force under hybrid boundary between ear plate anchor plate, this paper proposes a method for identifying conditions bending stiffness cables based on frequency method. First, influence parameters, namely, conditions, stiffness, inclination angle, linear density, was analyzed. Next, actual upper hinged support lower solid at both ends were determ...

The focus of this paper is the thick soft rock mass roof track roadway in No. 3606 panel Chaili Coal Mine. Due to its substantial thickness, susceptible damage and deformation during mining process. In order preserve integrity roof, a full anchor cable support scheme proposed after studying mechanism bolt-anchor support. supporting parameters feasibility were determined through experience numer...
