... clays was found to be inappropriate. The primary focus of this paper is to: (a) present and discuss the results of the horizontal pull tests previously reported by Oliphant et al (2006), exploring the influence of trench depth and speed of pipe movement; (b) compare the results with known plasticity...

... cannot be estimated with a great deal of reliability. It should be noted that the vertical scale in Figure 1 is exaggerated for illustrative purposes and typically ratio of trench depth to trench length is small (say 1%) so the problem may be reasonably treated within the framework of a small deflection...

Accurate depth control was essential, since otherwise the specified trench depth would not be achieved everyWhere, and the plough might require more force than the tug could apply...
