The grading of fine-grained soils is one fundamental properties, and studying how to obtain this information using in-situ methods essential. However, existing cone penetration tests (CPT) lack a direct approach for measuring particle size its content. In order address that issue, the relationship between tip resistance (qc) sleeve friction (fs) with these curve parameters (CPs) was established CPT. Finally, an expression curves based on results obtained from CPT presented. main conclusions...
The Yellow River Delta is located at the junction of and Bohai. impact function from river dynamics ocean tides make soil composition distribution in this area substantially complicated. In order to test variation layers Delta, were classified was calculated using cone penetration (CPT). following conclusions drawn: (1) measured mainly composed sensitive fine-grained soil, accounting for about 70% all types, content far-sea position higher than that offshore direction perpendicular...
Accurate knowledge of the mechanical properties deep-sea sediments and various parameters seafloor environment is extremely important for geological investigations. In this paper, a set self-developed 3000 m-level multiparameter CPTu in-situ integrated test system developed, which successfully solves technical problems existing in detection technology, hydraulic fine control penetration coaxial cable optical composite transmission etc. A multi-functional probe rod contains single 3 D...
This paper aims to provide a design basis for engineering disaster prevention and mitigation by accurately describing the spatial distribution of soil liquefaction. A group in-situ Cone Penetration Tests (CPT) was conducted evaluate seabed properties liquefaction potential Yellow River Subaquatic Delta. The factor safety against (FSL) index (LPI) were utilized investigate characteristics soils. findings are as follows: (1) delta is "near coarse far fine," with sand silt dominating onshore...
The Yellow River Delta is one of the most abundant offshore energy areas in China, and construction projects rapidly developing. In this paper, four typical regions different periods were selected as research objects. In-situ cone penetration tests (CPTs), geotechnical testing, electron microscope scanning soil type indexing (Ic) was used to classify identify layers. At same time, a modified calculation model based on CPT for shear wave velocity fine-grained seabed sought verified with...
The Yellow River Estuary is a typical constructive delta with complex sedimentary structure. To analyze the physical, mechanical properties, and structural characteristics of surface sediments in delta, reveal environment avoid geological hazards, cone penetration test (CPT) used for nautical situ testing evaluating effective internal friction angle (φ'). Four areas formed by diversion different periods are selected as research objects to perform CPT, particle size analysis test, scanning...
The soil composition in the Yellow River Subaquatic Delta is complex, and liquefaction a serious threat to safety of offshore projects. Two-dimensional evaluation cannot meet practical needs engineering. In this paper, in-situ cone penetration tests (CPT) were used investigate classification distribution soils. Liquefaction variability prediction analysis was performed for region by inverse distance weighting (IDW) full-cokriging methods using vulnerability index (LVI) tip resistance as...
