摘要:

SummarySoil shear strength is a property likely to affect the performance of cultivation implements. Existing methods of measuring this property have been found unsuitable for cultivated top soils, principally because of the difficulty of obtaining an undisturbed sample. A field method of determining shear strength is described in which a cylinder of soil is sheared in torsion and a moment/angle‐of‐twist (proportional to strain) curve obtained. From this the shear‐stress/angle‐of‐twist can be obtained mathematically. Where only the maximum shear strength is required a simplified method is given. A number of results using the apparatus on widely differing soil types is given, together with a comparison of some of these with results from the standard
