深海表层沉积物的强度和变形性质测量装置Device for measuring strength and deformation properties of deep-sea surface sediments

技术领域technical field

本实用新型涉及深海表层沉积物的强度和变形性质测量装置。The utility model relates to a device for measuring the strength and deformation properties of deep sea surface deposits.

背景技术Background technique

随着深海能源的开发利用,对于海底土体工程性质探测技术要求越来越高。目前国际上常用的有深海钻探、海底静力触探、表层挖泥斗取样、重力取样管取样和工程物探等方法和相应设备。深海钻探在国内基本上还是空白,深海海底静力触探已从国外引进,但这两种方法操作复杂、设备昂贵。又由于工程物探只能定性的分析海底土体的性质,而挖泥斗取上来的是扰动样,多用来分析土的类型,重力取样管可以将样品取回实验室进行物理力学性质测试,但经过取样和搬运过程的扰动,已使样品“失真”,不能准确反映原位土体的物理力学性质。因此在实际勘查中大多用的是挖泥斗取样,再结合工程物探的方法对深海土体物理力学性质进行定性分析,显然实际测量仍然不便。又,目前的研究成果已能方便地利用土体的阻力参数,分析计算出表层沉积物的强度、压缩性以及密实度、稠度状态和承载力等参数或指标,显然方便地测量出原位的土体的阻力参数,是十分必要的。With the development and utilization of deep sea energy, the requirements for detection technology of seabed soil engineering properties are getting higher and higher. At present, there are methods and corresponding equipment commonly used in the world such as deep-sea drilling, seabed static penetration, surface dredge bucket sampling, gravity sampling tube sampling and engineering geophysical prospecting. Deep-sea drilling is basically still blank in China, and deep-sea submarine static penetration has been introduced from abroad, but these two methods are complicated to operate and expensive in equipment. And because engineering geophysical prospecting can only qualitatively analyze the properties of the seabed soil, and the disturbed samples taken from the dredger are mostly used to analyze the type of soil. The gravity sampling tube can take the samples back to the laboratory for physical and mechanical properties testing, but After the disturbance in the sampling and handling process, the sample has been "distorted" and cannot accurately reflect the physical and mechanical properties of the in-situ soil. Therefore, dredger bucket sampling is mostly used in actual exploration, combined with engineering geophysical prospecting methods to qualitatively analyze the physical and mechanical properties of deep-sea soil. Obviously, actual measurement is still inconvenient. In addition, the current research results have been able to conveniently use the resistance parameters of the soil to analyze and calculate the parameters or indicators such as the strength, compressibility, compactness, consistency state and bearing capacity of the surface sediments. The resistance parameter of the soil is very necessary.
