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.

该伙伴关系方案涉及联合王国达勒姆大学与南非五所大学（比勒陀利亚大学、自由州中央技术大学、夸祖鲁纳塔尔大学、开普敦大学和斯泰伦博斯大学）就一个题为“工程实践非饱和土壤力学"的项目开展合作。在英国和南非，土壤的非饱和特性引起了许多岩土工程问题，包括由于承载力不足而导致的地基坍塌、由于过度地面隆起而导致的结构损坏、天坑形成、天然边坡和人造边坡的边坡失稳以及公路和铁路地层破坏。该网络由13名学术人员组成，将培训20名博士生。网络内的研究活动分为三个股：实验室和非饱和土的原位测试，数值模型的开发和工程问题的应用。网络合作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。
