中文摘要：
随着社会经济的不断发展,土力学所要分析和处理问题的范围越来越广,问题本身也越来越深入和复杂。这些问题主要是由于土与环境的相互作用而产生的。为了分析和处理这些问题,经典土力学需要拓宽和深入发展,它应该包含一些新的现象和新的变量以及相应的新理论。论述了土力学所面临的三大挑战,即①没有严格、统一和完备的土力学理论;②对更具一般意义的非饱和土的行为的研究不够充分,现有的认识也不完善;③没有在多种环境作用下土的统一和完备的多场耦合理论。还论及了其他一些超出经典土力学范围的问题。
英文摘要：
With the development of society and economy,the range of the engineering problems that soil mechanics has to deal with is increasing;and these problems also become more and more complicated due to the interaction between soils and environments.In order to deal with these problems,the classical soil mechanics is required to be generalized and developed in depth and scope to incorporate the effects of new phenomena and new variables on soil behaviours.Based on a historical review of the development of soil mechanics,it is suggested that the classical soil mechanics faces three challenges：（1） lack of a unified,rational and theoretical framework of soil mechanics;（2） the knowledge and understanding of unsaturated soil behaviours is insufficient;（3） lack of a unified,rational and theoretical framework for multifield coupling problems of soils under multiple environmental actions.Finally,some problems beyond the scope of the classical soil mechanics are discussed.
