Soil investigation is the main key in starting construction. Standard Penetration Test (SPT) and Cone (CPT) are field tests often used to estimate soil parameters for foundation design purposes. The SPT value (N-SPT) shows a correlation between CPT other parameters. At present, there have been many conventional correlations examining these correlations, but nonlinear nature of due very complex ...

statement of problem: it has been established that successful root canal treatment depends on the quality of obturation. deeper penetration of spreaders can improve the apical seal and the quality of the obturation. purpose: the aim of this study was to compare the initial penetration depth of spreaders during lateral condensation of 0.04 and 0.02 tapered gutta-percha master cones. materials an...

Pondasi tiang pancang merupakan struktur bagian bawah yang menumpu pada tanah keras atau tumpuan padat dan bekerja sebagai penopang berada diatasnya, jika bawahnya kokoh maka atas akan tetap berdiri kokoh, sebaliknya tidak kuat menahan atasnya runtuh, Penelitian ini dilakukan untuk mengetahui daya dukung pondasi tunggal kelompok dengan menggunakan metode Mayerhoff 1956 Luciano Decourt 1996 berd...

Because of the deltaic nature Netherlands, deep soft soil deposits are widespread. Due to population density exploitation underground space is vital for commercial developments and transport networks. Piles used as primary support elements in excavations, cut cover tunnels, quay walls, flood defences provide uplift resistance base tunnels basements. This paper examines empirical correlations li...

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 ...

The Canterbury Earthquake Sequence produced a spatial pattern of liquefaction-induced surface ejecta at an open field along Palinurus Road in Christchurch, New Zealand, that would not be expected based on simplified liquefaction evaluation procedures. Half the site discharged sand boils and other half did not. Two-dimensional fully-coupled nonlinear dynamic analyses (NDAs) were performed to exa...

this paper highlights the effect of silt content on cone tip resistance in loose silty sand. in this study, twenty-seven cone penetration tests are performed in saturated silty sand samples with several different silt contents ranging from 10 to 50 percent. the samples are consolidated at three overburden stresses including 100, 200 and 300 kpa. it is shown that, as the silt content increases, ...

This study evaluates granular liquefaction triggering case-history data using a nonparametric approach. This approach assumes no functional form in the relationship between liquefied and nonliquefied cases as measured using cone penetration test (CPT) data. From a statistical perspective, this allows for an estimate of the threshold of liquefaction triggering unbiased by prior functional forms,...
