<p>This paper reports the ground improvement and excavation of a cross passage between two shield tunnels for the construction of Tu-chen Line of Taipei Rapid Transit Systems. Jet grouting was conducted for soils around the cross passage before the tunneling ...

Lateral load tests were performed on a full-scale pile cap in clay before and after construction of shallow soilcrete walls produced by soil mixing and jet grouting on either side of the pile cap. This relatively simple approach increased the lateral resistance ...

An essential characteristic of this stretch is that it has been built under the water table by excavating in very heterogeneous soils, composed of granular soils and rocks of considerable resistance which has created numerous problems during the construction ...

Lateral load tests were performed on a full-scale pile cap in clay before and after construction of eight 1.5 m diameter jet grout columns to a depth of 3 m around the pile group. Jet grouting with a cement content of about 400 kg/m3 (20% by weight)increased ...

Jet grouting has increasingly become one of the ground improvement technologies used to address seepage concerns and to provide strength improvement of soils. The technique of jet grouting uses high pressure/velocity jet fluids to erode the existing soil and ...

<p>Ground Improvement techniques are often used to improve sub soil properties in terms of their bearing capacity, shear strength, settlement characteristics, drainage, etc. These techniques have a wide range of applicability from coarse grained soils to ...

<p>A brief overview of jet grouting in Brazil is followed by &ldquo;why and when&rdquo; basics in relation to ground improvement for safe tunnel excavating. A number of case histories are reported - mostly NATM tunnels involving what were seen as difficult, ...

The paper describes current United States practice for Deep Soil Mixing (over 12 meters in depth), and Shallow Soil Mixing for vertical barriers and stabilization/solidification, and Jet Grouting for horizontal and vertical barriers. Creating very low permeability ...

This paper presents a stabuilization treatment applied using jet grouting techniques for soils contaminated with elevated concentrations of cadmium hazardous substances
