摘      要：The last two to three decades have seen significant advances in the mechanics of unsaturated *** is now widely recognized that the fundamental principles in soil mechanics must cover both saturated and unsaturated ***,there is still a great deal of uncertainties in the geotechnical community about how soil mechanics principles well-established for saturated soils can be extended to unsaturated *** is even wide skepticism about the necessity of such extension in engineering *** paper discusses some common pitfalls related to the fundamental principles that govern the volume change,shear strength and hydromechanical behaviour of unsaturated *** also attempts to address the issue of engineering relevance of unsaturated soil mechanics.
