Title : Analysis on the Mechanical Behavior of the Interlayer Interface of a Recycled Composite Pipe with a Thin-walled Lining
LU Zhaohong, , WANG Kaibo, , WANG Zunce, , XU Yan, , LIU Haishui,
Abstract : In order to study the interlaminar mechanical behavior of regenerated composite pipes with thin-walled lining, tangential and normal tensile failure tests are carried out on the composite pipes with corroded defects and thin-walled stainless steel lining. Based on the test results, a finite element analysis model is established for the repaired pipes with corroded defects. The test results of test specimen under the effect of tangential force show that with the increase of pipe steel corrosion e

Title : Field Test and Positioning Analysis of Reinforcement of Deep Water Submerged Dam by Thrown Stones
HUANG Weidong, , YU Minghui, , YAO Shiming, , QU Geng,
Abstract : Submerged dam is a commonly used structure to control the reaches of a braided river, and it is generally located at the entrance of the inlet. The flows in these areas are often complex. It may cause downstream scouring after the completion of the submerged dam and the consequent uneven subsidence. Riprap reinforcement is an important measure of maintaining the function of the submerged dam. The conventional riprap reinforcement project is used in the bank protection. The traditional stone-thro

Title : Progressive Collapse Analysis of Levy Type Rigid Bracing Dome
GAO Zhanyuan, , XUE Suduo, , LUO Dajie, , YANG Weiqi,
Abstract : When Levy type rigid bracing dome is impacted by unexpected load, its structure may collapse continuously, resulting in property loss and casualties, therefore, it is necessary to analyze its progressive collapse performance. According to characteristics of rigid bracing dome, the threshold coefficients of members and its calculation formula were given, and the discriminant criteria and types of progressive collapse were proposed. Damage coefficient based on response difference was proposed, and

Title : Research on Thermal Hysteresis Behavior of Single-head PCP with Equal Thickness of Hydrogenated Nitrile in Heavy Oil Recovery
SHI Changshua, , CHEN Kailin, , ZHU Xiaohua,
Abstract : Progressive cavity pumps (PCP), which uses the ordinary nitrile rubber, are widely used in heavy oil production, and it is prone to failure of the core-burning perforation of the stator bushing. The expensive hydrogenated nitrile rubber is resistant to high temperatures but does not have precise use depth and cross-sectional parameters. In order to solve above problems, first of all, the rubber hyperplastic constitutive model of ordinary nitrile rubber and hydrogenated nitrile rubber is fitted b
