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 ...

<p>Measurements on back-fill grouting at Groene Hart Tunnel (GHT) are described and analysed. The research utilises TBM data, monitored grout pressures and measured rheological properties of tunnelling fluids. Grout injection strategy and vertical grout pressure ...

The development of strain and long instrumented postdriving grouted cylinder piles is presented.

This paper discusses some of the problems encountered with water ingress on the 72km of tunnels on this project. Grouting is always a significant portion of dam projects and with the quantities of water expected in the tunnels, was also going to be an important ...

Drilled displacement piles are installed by the displacement of soil and subsequent placement of fluid cement grout within the evacuated volume. Depending on the soil grain-size characteristics, soil behavior, in situ soil density, pile spacing, and pile diameter, ...

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 ...

<p>The Strood and Higham Railway Tunnel is some 3.7km in length and was originally built as a canal tunnel enabling boats to pass freely between the river Medway and the river Thames. The tunnel was excavated between 1819 and 1824 through reasonably competent ...

<p>In dam rock foundations, grouting is performed to improve water-tightness and reinforce weak parts. It is difficult to accurately estimate the improvements brought about by grouting, because the grouting is applied in the rock mass where it is not visible. ...

A new method of improving the engineering properties of soil foundations (GEOCOMPOSITE) was developed in the Institute of Environmental Geoscience of the Russian Academy of Sciences. This new technique is based on the principles of composite material creation. ...

The subsurface conditions for a proposed six-story $94M medical facility in Knoxville, Tennessee, consisted of a thick clay layer overlying an irregular weathered limestone bedrock surface. Because the design loads were significant and because of the sinkhole ...
