Abstract

The present invention provides a preparation method of a layered seabed soil sample used for a one-dimensional cylinder test. The preparation method comprises: drying coarse sand and fine sand, and blending the coarse sand and the fine sand according to different ratios to obtain layered soil samples; loading the samples, and adding the loaded soil sample into the main body cylinder part of one-dimensional cylinder test equipment according to a certain mode; and after adding the soil and water into the main body cylinder, standing the soil sample for a certain time, and carrying out saturationtreatment so as to obtain the layered seabed soil sample capable of being subjected to a seabed dynamic response test. According to the present invention, the preparation method has the simple and reliable operation, and can rapid prepare the layered seabed soil sample for seabed dynamic response test research.

Description

Technical field [0001] The invention relates to the field of marine engineering, and in particular to a method for preparing a layered seabed soil sample applied to a one-dimensional cylinder test. Background technique [0002] The real seabed is often layered due to geological origin. For example, the seabed supporting layer near Shanghai Yangshan Port is composed of twelve layers of soil, and layered seabeds are common in actual projects. At present, one-dimensional cylinder test equipment is widely used in the study of the response of seabed soil under the action of waves and other ocean loads. Therefore, it is necessary to study the preparation of layered seabed soil samples applied to one-dimensional cylinders. [0003] When the current test methods study the dynamic response of the seabed under wave loads, there are mainly tank tests and centrifuge tests, but the tank test and centrifuge test are limited in the depth direction of the seabed (the thickness of the seabed does ...
