This partnership programme involves collaboration between Durham University UK and five universities in South Africa (the University of Pretoria, the Central University of Technology, Free State, the University of Kwazulu Natal, the University of Cape Town and Stellenbosch University) on a project entitled "Unsaturated Soils Mechanics for Engineering Practice (UnsatPractice)". The unsaturated characteristics of soils give rise to many geotechnical problems in the UK and in South Africa including collapse of foundations due to inadequate bearing capacity, structural damage due to excessive ground heave, sinkhole formation, slope instability both in terms of natural slopes and man-made embankments, as well as road and railway formation failure. The network comprises 13 academic staff and will train 20 PhD students. The research activities within the network are divided into three strands: laboratory and in-situ testing of unsaturated soils, development of numerical models and applications to engineering problems. The network partners will generate significant follow-on projects by seeking new research funding from national and international research councils and agencies and will establishing formal long-term sandwich PhD programmes before the end the award period.

这一伙伴关系计划涉及英国达勒姆大学与南非五所大学(比勒陀利亚大学、中央科技大学、自由州立大学、夸祖鲁·纳塔尔大学、开普敦大学和斯泰伦博什大学)在题为“用于工程实践的非饱和土力学(Unsat Practice)”项目上的合作。土的非饱和特性在英国和南非引发了许多岩土工程问题，包括地基承载力不足导致的地基坍塌、因地面隆起过大而造成的结构性破坏、天坑的形成、天然斜坡和人造路堤的斜坡不稳定，以及公路和铁路的形成故障。该网络由13名教职员工组成，将培训20名博士生。该网络的研究活动分为三个方面：非饱和土壤的实验室和现场测试、数值模型的开发和工程问题的应用。网络伙伴将通过从国家和国际研究理事会和机构寻求新的研究资金来产生重要的后续项目，并将在奖励期结束前建立正式的长期三明治博士课程。
