A new hyperbolic model for generating P-Y curves is developed for use in lateral analyses of cemented soils (a C-φ soil with both cohesive intercept and friction angle), and includes degradation of the static loading soil response to model the effects of load ...

The load test program for the Audubon Bridge project provides a comparison of the performance of base grouted and ungrouted shafts on large diameter foundations in sand. Comparison of several field load tests at the two pylon foundations indicate that the ...

This paper describes the results of a detailed analysis of a loess deposit at the deep foundations test site established by the Kansas Department of Transportation. Multiple CPT, SPT, and pressuremeter tests were conducted as part of the investigation. This ...

This manual presents the state-of-the-practice for design and construction of continuous flight auger (CFA) piles, including those piles commonly referred to as augered cast-in-place (ACIP) piles, drilled displacement piles, and screw piles. CFA pile types, ...

The use of base grouting (tip grouting) to enhance the axial capacity of drilled shaft foundations can achieve improvements in economy and reliability for many types of projects and soil profiles. Recent experiences on a range of different construction projects ...

Although pressure grouting beneath the tips of drilled shafts had been used successfully worldwide for close to 4 decades,it has remained relatively unused in the United States in part due to the absence of a rational design procedure. This paper briefly discusses ...
