9222669 Ho This action is to instrument 0a permanent reinforced earth structure or tried-back wall located in a seismic region of California. This geotechnical structure utilizes inclusions (such as tie-backs, soil nails, reinforcing strips and geotextiles) to provide stability. The purpose of the instrumentation is to provide a means to collect data on the response to a future earthquake: the response of these structures to seismic loading is unknown. The measured response will be compared to the predicted performance, thereby providing the necessary link between design and performance. Periodic maintenance of the instrumentation and the retrieval of measured data will be coordinated between the U.S. Geological Survey and Washington State University. ***

9222669 Ho此操作是为了测量位于加利福尼亚州地震区的永久性加筋土结构或试背墙。这种土工结构利用夹杂物(如系带、土钉、加筋带和土工布)来提供稳定性。该仪器的目的是提供一种手段来收集关于未来地震反应的数据：这些结构对地震荷载的反应是未知的。测量的响应将与预测的性能进行比较，从而在设计和性能之间提供必要的联系。仪器的定期维护和测量数据的检索将由美国地质调查局和华盛顿州立大学协调。***
