The phenomenon of soil liquefaction can be an induced effect earthquake shaking where the saturated loses some or all its bearing capacity and stiffness. Likewise, increase water pressure in pores under seismic wave causes a decrease shear strength. As result, becomes liquefied susceptible to producing permanent deformations. is generally unpredictable, neglecting it influence stability structu...

The liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like Standard Penetration Test (SPT), Cone Penetration Test (CPT) and Shear Wave Velocity (Vs). In this regard, this study attempts to compare the results of the SPT based on the simplified procedure proposed by Seed and Idriss...

Commercial cone penetration testing (CPT) equipment was adapted to allow penetrative testing in hard polar firn to depths of 10m. The apparatus is hydraulically driven, rate-controllable and able to penetrate firn with a resistance of 10MPa. It can be mounted on many types of typical polar vehicles, requiring connection to only hydraulics and 12V electricity. Data recorded include both cone tip...

The Standard Penetration Test (SPT) and Cone Penetrometer Test (CPT) have become industry standards for subsurface geotechnical investigations using small diameter (<8-in. [20-cm]) borings and soundings. Both procedures have evolved over a period of 100 and 70 years, respectively, and have been adopted as ASTM standards. Each procedure has certain advantages over the other, but both can elicit ...

Frameworks for estimating soil properties from CPT penetration resistances must account for the effects of overburden stress on both the penetration resistance and the soil property of interest, including how such effects vary with soil type. For example, common procedures for estimating the liquefaction resistance of sands include functional terms that account for the effect of overburden stre...

In the simple buildings, shallow foundations can be used to support construction above them. This foundation has various types, including type of footplate which calculated using Terzaghi equation. equation, it requires dimension parameters footing and soil material such as cohesion volume weight laboratory testing obtain it. Meanwhile, Schmertmann provides an equation bearing capacity factor i...

In geotechnical field investigations, cone penetration tests (CPT) are increasingly used for ground characterization of fine-grained soils. Test results different parameters that typically visualized in CPT based data interpretation charts. this paper we propose a novel methodology which is on supervised machine learning permits redefinition the boundaries within these charts to account unique ...

Perencanaan pondasi tiang memerlukan data penyeledikan tanah. Oleh karena itu, diperlukan dan analisis dari penyelidikan tanah yang akurat guna menghindari terjadi kegagalan pada tiang. Penyelidikan dengan pengujian Standard Pentetration Test (SPT) Cone Penetration (CPT) merupakan paling sering digunakan di beberapa proyek. Pada studi ini, dilakukan perhitungan daya dukung berdasarkan SPT CPT, ...
