In this paper, effect of the dip angle, stiffness and design depth of bolt on the horizontal displacement of tension anchor supporting structure was carried out by FLAC3D.
DESIGN OF PRESTRESSED ANCHOR BOLTS AND SIMULATING CALCULATION BY FINITE ELEMENT METHOD FOR ANCHOR BOLT SPRAY SUPPORT IN BIG SPAN TUNNEL WITH HARD ROCKS
,and give out its own view about the selection of development of the hydropower station, layout of the underground cavern mass, selection of method for stability analysis on the surrounding rocks and support, and design of the rock anchorage crane beam.
the construction sequence that the anchorage is excavated after the tunnel is reasonable by comparing vertical displacement caused by the tunnel construction and designed cable force;
Steel rod ends are connected with the lateral plane and end-plate connections anchored by steel rod and prestressed,Fill in the anchor buried on the friction plate to maintain the stability of the retaining wall support mechanism.
The membrane enzyme with a hydrophobic peptide anchor was more sensitive to anions and to changes in pH and composition of the medium than the soluble enzyme without anchor.
An ultrasonic linear motor is proposed and fabricated by using the longitudinal and bending vibration double mode bolt-clamped Langevin type transducer to meet high power and speed requirements in the aerospace and semiconductor industries.
In the elastic and thermo-elastic Finite Element Method (FEM) calculations, the effects of the bolt pitch distance, flange rigidity and flange thickness were examined on the interface stress distributions.
Along with multiple antitumor drug resistance, MCF-7Dox cells demonstrate elevated resistance to anchorage-dependent apoptosis (anoikis) and enhanced in vitro invasive activity.
Pulsed-field electrophoresis of DNA was used to demonstrate that ADP-ribosylation stimulates the cleavage of DNA loops at the sites of their anchorage to the nuclear matrix in nucleoids of human mononuclear leukocytes and rat brain neurons.
A hypothesis has been proposed that the regions of DNA loop anchorage to the nuclear matrix are the preferential sites (hot spots) of illegitimate recombination mediated or triggered by topoisomerase II of the nuclear matrix.
Tumor necrosis factor (TNF)-α-converting enzyme (TACE) is the major protease responsible for processing pro-TNF-α from membrane-anchored precursors to secreted TNF-α.
A corresponding computer program is developed and employed for studying the seismic response control of a self-anchored suspension bridge with a main span of 350 m.
The sorption capacity was found to be 2.39 and 8.47 mg g-1 for U(VI) and Th(IV) on apricot stone anchored with oxalic acid and 2.3 and 9.18 mg g-1 for the sorbent anchored with succinic acid, respectively.
