1.1本指南提供了沉降平台的制造、安装、操作和读数的建议设计和程序，以确定基础、填土沉降的大小和速率，或通常在填土或路堤荷载下的大小和速率。描述了两种类型的沉降平台——通过外部基准点的高程测量进行监测的沉降平台和包括内部参考系统的沉降平台，内部参考系统支撑在相关可压缩层下方的不屈服土壤或岩石上。 1.2 本指南并非旨在解决与其使用相关的所有安全问题（如有）。本指南的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.3 本指南提供了有组织的信息收集或一系列选项，并不推荐具体的行动方案。本文件不能取代教育或经验，应与专业判断结合使用。并非本指南的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。

1.1 This guide provides recommended designs and procedures for the fabrication, installation, operation, and reading of settlement platform to determine the magnitude and rate of foundation, fill settlements, or bothgenerally under a fill or embankment load. Two types of settlement platforms are described - those be monitored by elevation surveys from an external bench mark and those that include an internal reference system supported on unyielding soil or rock beneath the compressible layer(s) of interest. 1.2 This guide does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this guide to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.3 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action.
