Numerical Simulation of the Mechanical Properties of Gas Hydrate-Bearing Marine Sediments Using the Discrete Element Method Under Depressurization Conditions
摘要
Abstract
Depressurization mining can cause significant changes in the macroscopic mechanical properties of marine sedimentary energy soil,while cemented type is the main type of natural gas hydrate stored in the marine sedimentary energy soil reservoir.Therefore,it is of great significance to study the mechanical properties of cemented deep sea sedimentary energy soil under depressurization mining conditions to improve the efficiency of natural gas hydrate exploitation and prevent marine disasters.This article studies the effects of bonding and damage on cemented deep sea sedimentary energy soil during depressurization mining,constructs a three-dimensional discrete element numerical model,and analyzes the influence of confining pressure,saturation and damage on the mechanical properties of cemented deep sea sedimentary energy soil under depressurization mining conditions.The research conclusions have good reference significance for the research of natural gas hydrate exploitation in the sedimentary energy soil reservoir of the deep sea.关键词
