Small-size calibration tank for seabed soil static cone penetration test
The invention relates to the technical field of marine geotechnical engineering, in particular to a small-size calibration tank for a seabed soil static cone penetration test. The tack comprises a tank body, a test sample cavity is formed in the tank body, a horizontal stress adjusting mechanism is arranged in the circumferential direction of the test sample cavity, a vertical stress adjusting mechanism is arranged at the bottom of the test sample cavity, and the horizontal stress adjusting mechanism and the vertical stress adjusting mechanism do not communicate. According to the tank, it is guaranteed that research can be carried out under the condition that the sample quantity is small, the whole test period is about 10 hours, and the sample preparation and test efficiency is greatly improved; meanwhile, boundary conditions of the calibration tank can be dynamically controlled through the horizontal stress adjusting mechanism and the vertical stress adjusting mechanism, so that the influence of the boundary conditions on the CPT test is avoided, the accuracy of samples and the test is ensured to a certain extent, and a field test condition is met; and in addition, the stress of a simulated covering layer can reach 5 MPa, and the actual situation of field test is met to a great extent.
本发明涉及海洋岩土工程技术领域，具体涉及一种用于海底土静力触探试验的小体积标定罐。包括罐体，所述罐体内设置有试验样品腔，所述试验样品腔的周向设置有水平应力调节机构，所述试验样品腔的底部设置有垂直应力调节机构，所述水平应力调节机构和垂直应力调节机构不连通。本发明能够保证样品量少的情况下展开研究，整个测试周期大约需要10小时，也大大提高了制样和试验效率。同时，本发明通过水平应力调节机构和垂直应力调节机构实现了标定罐动态控制边界条件，避免了边界条件对CPT试验的影响，在一定程度上保证了样品和试验的精准度，符合现场测试情况。此外，本发明的模拟覆盖层应力可以达到5兆帕，也在更大的程度上满足现场测试的实际情况。
