9712602 This Small Grant for Exploratory Research (SGER) award is funded to initiate efforts to provide guidelines for assessing, controlling, and monitoring ground movements and building damage that are direct and uncomplicated, that will be accepted by contractors, designers, and preservationists, and that will aid in the provision of improved, adequate, and economic protection of structures. The research will develop model tests involving four large tieback walls, which will be extensively instrumented and monitored during testing by excavation. Models will be used also to investigate scaling relationships and interaction between ground, retaining walls, and surrounding structures, during and after excavation. Results of analyses will be compared with data from previous and current field cases. These efforts will be used to support the development and assessment of guidelines for controlling damage. By capitalizing on their strong existing cooperative efforts with industry, the principal investigators will formulate new criteria that will result in safer, more realistic, and more economical control of ground movements, while providing a higher level of protection for historic and urban structures. ***

9712602 这项探索性研究小额赠款（SGER）奖的资助旨在为评估，控制和监测地面运动和建筑物损坏提供指导方针，这些指导方针是直接和简单的，将被承包商，设计师和建筑师接受，并将有助于提供更好，充分和经济的结构保护。 该研究将开发涉及四个大型回接墙的模型测试，在挖掘测试期间将进行广泛的仪器和监测。 模型还将用于调查开挖期间和之后地面、挡土墙和周围结构之间的比例关系和相互作用。 分析结果将与以往和当前实地案例的数据进行比较。 这些努力将用于支持制定和评估控制损害的准则。 通过利用他们与工业界现有的强有力的合作努力，主要研究人员将制定新的标准，从而对地面运动进行更安全、更现实、更经济的控制，同时为历史和城市结构提供更高水平的保护。 ***
