The use of CPTu in soft soils are widespread. Usually, the CPTu tip resistance measures soft soils response as soil resistance as well as pore water pressure due to penetration of the cone during insertion into the soils. However, when CPTu is conducted in very soft soils and ultra-soft soils, the soil resistance is very low, and pore pressure domi...

Embankments on soft soils have been a research interest of geotechnical engineers for decades. This topic is no exception to the Malaysian Trial Embankments constructed in 1988. Specifically, two embankments of 3 m and 6 m were constructed on the original ground, which means no soil improvement was performed to the foundation soils. Geotechnical in...

Abstrak Artikel ini memaparkan kajian analisis-balik penurunan tanah pada pekerjaan reklamasi di Makassar menggunakan program berbasis Metode Elemen Hingga (MEH). Perhitungan dilakukan dengan menggunakan pendekatan dua dimensi (2D) dan jenis model regangan bidang. Adapun tahapan penimbunan disimulasikan sesuai dengan tinggi dan waktu konstruksi di...

CPT-SPT correlation is one of the most common correlations made in geotechnical practice. Researchers have been proposed such correlations for both cohesive and granular soils. However, correlations for a particular soil, for instance, volcanic soils, are still limited. This paper presents CPT-SPT correlations of volcanic soils in Kediri, East Java...

Piezocone is one of the most useful tools to identify soil conditions, especially when the ground is soft. The interpretation of the results is quite challenging because it requires knowledge and understanding of the cone penetration mechanism. In this study, a numerical model based on the finite-element method was used to study the soil response o...

Pendidikan merupakan modal utama bagi setiap individu untuk menghadapi masa depan. Pendidikan Anak Usia Dini (PAUD) sebagai pendidikan tahap awal berfungsi untuk mengembangkan potensi dan membentuk karakter anak. Pada tahap ini, guru membantu pertumbuhan dan perkembangan fisik, kecerdasan, kognitif, bahasa, dan sosio emosional anak. Proses pendidik...

Ground movement phenomena were detected at abutment A2 of Cigombong Bridge, causing the abutment to hit a girder. A thorough investigation has been performed by inspecting the structure condition and nearby landslide occurrences directly on site. Additional borings with Standard Penetration Test (SPT) were also conducted to evaluate the actual soil...

Phenomena of slope movement were identified on the southern side of Penggaron Bridge, which is Abutment 2 (A2) and Pier 9 (P9), at the end of 2011. Geotechnical instrumentation gives a result that the landslide movement is instead directed toward the North-East direction. A common way of back-analysis is by assuming that the Safety Factor (SF) is e...

Gunung Semeru merupakan salah satu Gunung Api yang masih aktif di Kabupaten Lumajang - Provinsi Jawa Timur, Indonesia. Dalam sejarah vulkaniknya, Gunung Semeru masih aktif mengeluarkan lahar serta material piroklastik yang terdeposit di sekitar lereng dan kawah. Pada saat ini terdapat 3 alur sungai dimana alur sungai tersebut merupakan alur sedimen...

Piezocone test (CPTu) is one of the most versatile tools for geotechnical investigation. It is commonly used for soil type identification, soil stratification, and geotechnical parameters determination. In soft soils, the CPTu test is very important because of its capability of pore pressure measurement. This paper presents the result of CPTu test...

Fenomena liquifaksi pada Gempa Palu Donggala 2018 merupakan satu kejadian unik dan menimbulkan kerusakan dahsyat. Salah satu fenomena liquifaksi yang lengkap dapat dikatakan ditemukan di desa Lolu, Kecamatan Jono Oge. Mulai dari sand blows, lateral spreading, liquifaksi alir maupun liquifaction induced landslide ditemukan di area ini, dengan keunik...

The 30 September 2009 Padang Pariaman (or West Sumatera Earthquake) (M = 7.6 USGS) has caused severe damages of buildings and infrastructures and fatalities. Many of the buildings failed may be due to the low quality of the structures or due to that most buildings were designed Indonesian code SNI 1726-2002, and many of them failed because of the o...

Piles have been used as foundations for a very long time. Their use is often combined in groups to support higher loads. This paper presents a numerical study using finite element method to study the behavior of pile in groups, in particular: the load transfer. Pile foundation of a tower resting on sand lenses is modeled using finite element-based...

Bored pile foundation is used to transfer structural load to soils. The construction method is by drilling the soils up to the designed layer, rebars inserted and concrete poured using tremie method. The possible imperfection in pouring concrete is difficult to detect but could lead to low bearing capacity of the foundation. To obtain a quality bor...

One of important input in wave propagation in pile driving analysis is the magnitude of damping in large shearing strains or displacement. The uncertainty of this parameters has been elaborated using matching in Pile Driving Analyzer (PDA) of Dynamic Load Test (DLT) where force measured by strain gauges are being matched with the velocity measured...

Excavation is one of the most common work found in a project, especially in a high-rise building project. Present day, excavation goes deeper and sometimes it is constructed on soft soils. Therefore, an appropriate analysis must be conducted in order to assure a safe excavation. A case study takes place in an apartment project in Central Jakarta, I...
