High-pile wharf horizontal bearing capacity and static-dynamic characteristic in-situ overall detecting method

Abstract

The invention discloses a high-pile wharf horizontal bearing capacity and static-dynamic characteristic in-situ overall detecting method. The method is used for a horizontal movement detecting a state of loads, including horizontal load applied to measure the deformation of rubber fenders detection or horizontal loads, pier structure under horizontal load deformation force and displacement detection, static and dynamic traits and so on. And based on the test data, combined with the raw survey data to determine the design of the ship pier design, level design, loading docks and other relevant information and data base to determine the ability to work in a high - pile under lateral loads, structural dynamic behavior, assess the high-pile wharf structural quality and usage. Is one of the most direct and most reliable test method, it can more accurately assess the actual level of the active marina pier on static and dynamic load capacity and operating characteristics of the pier inspection, safety assessment, repair and reinforcement and renovation work provide a scientific basis.

Description

technical field [0001] The present invention relates to a detection method of port hydraulic structures in water conservancy projects, in particular to a method for overall detection of the horizontal bearing capacity and static and dynamic properties of built high-pile wharves, which is the most direct and reliable principle bit test method. Background technique [0002] High-pile wharf is a common and important wharf structure, which is widely used in soft soil areas along the coast of my country and along the Yangtze River. Ship loads are important horizontal loads for high-piled wharves, and sometimes even control loads. Affected by climate and environmental factors, as many as 89% of the docks in my country's seaports have been used for 7 to 25 years and suffered varying degrees of corrosion damage; generally, after about 10 years of use, premature failure or even complete failure due to insufficient durability of high-piled docks is common. phenomenon of damage. The ...

AI Technical Summary

Problems solved by technology

For the severely degraded high-pile wharf, can the health level of the wharf meet the requirements for safe service? Can the horizontal bearing capacity and working performance level of the built or newly built high-piled wharf meet the use requirements or design requirements? There are many uncertain factors that affect the bearing capacity of high-piled wharves. The decline in the bearing capacity of high-piled wharves is often not accurately determined through the detection of wharf components. Only through the overall load test can its bearing capacity be evaluated.

At present, research on the detection of high-piled wharf properties is mainly focused on the individual components of the wharf, and there is no known method for in-situ overall detection of the working behavior of built high-pile wharves under horizontal dynamic and static loads
