Linear extensibility of soils
NettetSand boils, a common indication of soil liquefaction, are more frequently observed in the lower portions of a lateral spread. Lateral spreading is defined here to include only lateral sliding of gently sloping ground due to soil liquefaction at relatively shallow depths, and does not refer to the large horizontal Nettet14. feb. 2005 · Soil Research is an international journal of soil science publishing high quality research on: soil genesis, ...
