摘要：在基坑自测的基础上，结合第三方监测单位的数据共享，判断基坑安全状态，能够有效的为基坑安全保驾护航。本文基于华新城居住区615地块职工安置住宅项目，介绍了施工过程中出现的错索内力监测点数据报警的相关情况。其发生的主要原固为：支护桩施工后局部场地未夯填密实，基坑周边也未做硬化防水处理，形成了雨水下渗通道，超时基雨诱发的深层土体沉降引超了错锚索内力整测数据报鲁。文中对监测数据报警情况产生的原固及其他相关整测数据均进行了系统分新，精此对基抗当时的整体安全状况进行了评估。同时，施工现场有针对性的采取了加强排水、基坑周动硬化防渗、加强仅器观测及人工返视等措施。并介绍了类似情况可能用到现场应急处置措施，保证了基坑的安全稳定运行。

Abstract: Based on self-test pit, combined with third-party monitoring unit of data sharing, to determine the security status of excavation can be effectively used as a base pit escort. Based on the completed construction of staff building projects in 615 block in Guanghua New Town, it introduced the relevant situation occurred during the construction of internal force anchor monitor. The main reasons are summarized that the construction site near the supporting pile is not filled dense, also not enough hardened around foundation waterproofing to form the rainwater infiltration channel, and short-time rainstorm induced deep soil subsidence by deep internal anchor forces alarm in monitoring. In this paper, the causes of monitoring data and other relevant monitoring data are analyzed systematically, so as to evaluate the overall safety condition of the foundation pit. At the same time, the construction site have to take the strengthening drainage, around the foundation pit hardening seepage, strengthen the observation instrument and artificial inspections and other measures, and the similar situation may be used on-
site emergency disposal measures, to ensure the safety and stable operation of the foundation pit Keywords: Excavation engineering; Anchor internal force; Data alarm
