Method for comprehensively verifying bearing capacity of steel sheet pile

Abstract

The invention discloses a method for comprehensively verifying bearing capacity of a steel sheet pile. Instruments mainly comprise an inclinometer, a total station and a strain gauge; the method for comprehensively verifying bearing capacity of the steel sheet pile uses a plurality of calculation methods and a large amount of manual data processing to establish a multi-variable steel sheet pile safety and stability evaluation model, a soil displacement change model along time, a steel sheet pile inclination degree change model along time and a steel sheet pile stress and strain change model along time; the multi-variable steel sheet pile safety and stability evaluation model can solve a safe and stable boundary surface through a large amount of data and the corresponding loss function, thethree time change models can clearly know the current change trend and predict the future change trend, and the method has high efficiency and strong practicability, no specific environmental conditions and other advantages, so the method can be widely applicable to comprehensive analysis of safety and stability problems.

Description

technical field [0001] The invention relates to the technical field of deformation monitoring of steel sheet piles, and more specifically, to a method for comprehensively analyzing the safety and stability of steel sheet piles. Background technique [0002] As a special type of steel sheet pile, the steel sheet pile is pressed into the ground with a pile driver and a vibrating hammer to form a continuous sheet pile wall, which is used as a temporary retaining and water retaining support structure for deep foundation pit excavation. The steel sheet pile has the advantages of high strength and rigidity, light structure, tight joint, good durability, good water tightness, simple construction, fast speed, good durability, small operation site occupation and reusability. With the rapid development of my country's economy and the intensification of urbanization process, the utilization rate of underground space has been greatly improved, and people pay more and more attention to t...

Problems solved by technology

[0004] With the application of steel sheet piles in actual engineering more and more widely, the production of steel sheet piles has also appeared a thriving situation. Some researches have also been carried out on the stress of steel sheet piles, but the current research is far from meeting the requirements of engineering production. There is an urgent need for a systematic method to systematically evaluate the safety and stability of steel sheet piles
