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.

该合作伙伴计划涉及英国达勒姆大学与南非的五所大学（比勒陀利亚大学，中央技术大学，自由州，自由大学，夸祖鲁·纳塔尔大学，开普敦和斯特伦博斯大学）在一个标题为“工程学实践机制（Unsatpractice）”的项目上。土壤的不饱和特征引起了英国和南非的许多岩土技术问题，包括由于轴承能力不足，由于地面过度而导致的结构损害，污水坑形成，斜坡不稳定，在自然坡度和人造堤防方面，以及道路和道路形成失败，斜坡不稳定。该网络由13名学术人员组成，将培训20名博士学位学生。网络中的研究活动分为三个股：实验室和非饱和土壤的现场测试，开发数值模型以及对工程问题的应用。网络合作伙伴将通过寻求国家和国际研究委员会和机构的新研究资金来产生重大的后续项目，并在颁奖期结束之前建立正式的长期三明治博士学位计划。
