In this paper, application of energy-based excess pore pressure generation model proposed by Park et al. (2008) to develop an improved model for the analysis of liquefaction potential and to predict excess pore pressure (EPP) is examined through experimental and analytical investigations. For more realistic description of the dynamic responses of saturated sand undrained dynamic triaxial tests ...

In various aspects, peat soil is different from mineral soil. Peat a biogenic deposit that emerged within the last 10,000 years, during post-glacial (Holocene) era. soft unable to support external loads without experiencing significant deformations. Tyre pressure automobiles and/or aeroplane wheels on paved surfaces creates traffic load, which can manifest as static or dynamic types of loading....

Comprehensive field investigations into the axial cyclic loading behaviour of open-steel pipe piles driven and aged in low-to-medium density chalk identify conditions under which is stable, unstable or metastable. Post-cycling monotonic tests confirmed that stable cycling enhanced pile capacity marginally, while cases suffered potentially large losses shaft capacity. Metastable led to intermedi...

An experimental investigation of multiple seepage-induced suffusion and its impact on the mechanical responses internally unstable gap-graded soil, with a fines content 25%, is presented in this paper. Using modified triaxial erosion apparatus, redesigned seepage control system, tests under conditions, as well undrained monotonic cyclic compression tests, are performed. It found that seepages c...

A new evaluation method for the dilatancy of fine-grained soils based on monotonic and cyclic undrained triaxial tests has been established using two elasticity approaches: isotropic transverse hypoelasticity. The clays, Kaolin Lower Rhine Clay, with also shows that is dependent stress ratio, void straining direction along intrinsic material parameters. Similar to sand, we can observe a Phase T...

Due to the long-term effect of cyclic traffic loads, accumulated deformation red clay subgrades is increasing, strength decreasing, and problems such as uneven settlement are occurring. In order improve stability durability subgrade, this paper analyzes effects stress ratios compactness on development dynamic elastic modulus saturated clay. This achieved through triaxial tests in Qingyuan Count...
