SGER: Water Stabilization Using Microparticles

在强地震中，由于土壤液化，位于可液化土壤(如松散的饱和砂土)上的建筑物可能会受到相当大的破坏。在不破坏建筑物和/或公共设施及其周围结构的情况下，在建筑物下进行传统的就地土壤改良是困难和昂贵的。这一行动是为了支持一项探索性研究计划，该计划涉及一种拟议的新解决方案--固定孔隙水。目的是验证这种方法的实用性。该方法使用定制的微粒来减少孔压积累。研究了两种安装微粒子的方法。该解决方案未经测试，是高科技化学、化学工程和土木工程的混合体。在建筑物下面安装水凝胶需要特殊的水凝胶微粒，这种微粒表现出延迟激活的特性，从而使所有的水凝胶在激活发生之前就已经到位。如果成功，这种方法将在土木工程、化工、农业工程和医学中得到应用：固定化孔隙水可用于大坝修复、环境地下水问题、供水和垃圾填埋场隔离等项目。了解定制微粒的结构可能会影响医疗递送技术和涂层技术。

Considerable damage can occur to buildings sited on liquefiable soil (such as loose saturated sand) during strong earthquake shaking as a result of soil liquefaction. It is difficult and expensive to perform conventional in situ soil modification underneath a building without damaging the building and/or utilities and surrounding structures.This action is to support an exploratory research program involving a proposed new solution - to immobilize the porewater. The objective is to verify the practicality of this approach.The method uses custom microparticles to reduce pore pressure buildup. Two methods of installing the microparticles are investigated. This solution is untested, and is a blend of high technology chemistry, chemical engineering and civil engineering. Installing the hydrogel under a building will require special hydrogel microparticles that exhibit time-delayed activation, thus enabling all the hydrogels to be in place before activation occurs.If successful, the method will have applications in civil engineering, chemical engineering, agricultural engineering, and medicine: The immobilization of porewater can be used to undertake projects in dam rehabilitation, in environmental groundwater problems, water supply, and landfill isolation. Learning about the construction of custom microparticles may impact medical delivery technologies, and coating technologies.
