... for the construction of bored piles (drilled shafts) and diaphragm walls since the early 1990s. They are used, in part, because of their rheological properties, especially their shear-thinning behavior, but to date research has focused on clean fluids and little also has been reported on the effects of reuse under...

...Zeng-Zhen Qian; Xian-Long Lu; Wen-Zhi Yang Drilled shafts have been applied to withstand the axial uplift load for transmission towers in Gobi, a common geological formation in Northwest China. This study elucidated the uplift behavior of drilled shafts in the Gobi gravel. Nineteen full-scale...

...Suthan Pooranampillai; Sherif Elfass; Walt Vanderpool; Gary Norris While post grouting of drilled shaft tips is an acknowledged means of mobilizing shaft base resistance at low values of displacement, much uncertainty exists among engineering professionals as to the conditions under which...

...KD Soo; KH Woo Numerical and experimental model studies were carried out to evaluate the base condition of drilled shafts. Base conditions such as free, fixed, rock-socketed, and soft-bottom were considered. To simulate the base conditions, mock-up shaft models made of cement mortar were used...

... and Tolosko (1999) presented and examined methodologies for obtaining the ultimate capacity from proof test data for driven piles. Load test data on drilled shafts supporting the H-3 freeway viaduct on the island of Oahu in Hawaii are used to test six extrapolation techniques by incrementally truncating...

.... KEYWORDS: model tests, sands, foundations, drilled shafts, inclined loading, cyclic, instrumentation, data acquisition Introduction Drilled shafts are used commonly as the foundations for electrical transmission line (TL) structures, which impose static and cyclic (repeated) inclined loads...

...SW Agaiby; FH Kulhawy; CH Trautmann An extensive large-scale laboratory model testing program was developed to assess the behavior of drilled shafts under lateral and moment loading. Because of the large scale of the testing, little information was available in the literature on sand deposit...
