Research Equipment for Geomechanics Testing

首席研究员目前获得了美国国家科学基金会的拨款，允许他研究深挖支撑系统上开发的土压力，例如城市主要建筑的深地下室和地铁。他正在进行实地测量，获取土壤样本并测量其物理性质，并进行理论分析。这笔赠款是为了提供资金购买两项专门的土壤测试设备，这些设备是测量土壤样本的相关物理性质所需的。这些产生的土壤特性将被纳入分析中，以开发更好的方法来预测设计时的土压力。

The principal investigator currently has an NSF grant to allow him to study earth pressures that are developed on support systems for deep excavations, e.g., for deep basements of major buildings in cities, and for subways. He is taking field measurements, obtaining soil samples and measuring their physical properties, and performing theoretical analyses. This grant is to provide funds to purchase two items of specialized soil testing equipment that are needed to measure relevant physical properties of the soil samples. These resulting soil properties will then be incorporated into the analyses to develop better methods of predicting earth pressures at design time.
