摘　　要：基坑监测对保证基坑安全施工至关重要,深层水平位移是基坑监测的重要手段。目前深层水平位移大多采用滑动测斜仪进行测量,但随着基坑监测信息化水平的逐步提高,固定式测斜仪的应用亦在逐步推广中。固定式测斜仪是一种常用于支护结构、地下工程等长期稳定性监测的设备,稳定性和测量精度较高,适用于长期稳定性监测。本研究通过室内室外实验,验证了固定式测斜仪测量支护桩深层水平位移的可行性,对深基坑支护结构深层水平位移监测技术的发展,具有较高的现实意义。Foundation pit monitoring is crucial for ensuring the safe construction of foundation pits,Horizontal displacement monitoring of deep soil is an important aspect of foundation pit monitoring.At present,sliding inclinometers are mostly used for measuring deep horizontal displacement,but with the gradual improvement of information technology in foundation pit monitoring,the application of fixed inclinometers is also gradually being promoted.Fixed inclinometers are commonly used for long-term stability monitoring of support structures,underground engineering,and other structures.They have high stability and measurement accuracy,making them suitable for long-term stability monitoring.This study verified the feasibility of using a fixed inclinometer to measure the deep horizontal displacement of support piles through indoor and outdoor experiments,and has high practical significance for the development of deep horizontal displacement monitoring technology for deep foundation pit support structures.
