Study on Development and Application of Modern Surveying Technology

In building construction,deep foundation as the most important point of security control must be controlled in the whole construction process.The paper researches the engineering measuring technology—deep foundation engineering monitoring.Combining with the construction case of deep foundation,it analyzes and discusses the monitoring and implementation of the horizontal displacement and layered settlement of deep soil from monitoring frequency,monitoring cycle,monitoring control indicators,monitoring method and data processing method,monitoring warning and alarm feedback measures and monitoring quality guarantees measures,hoping to be helpful for the construction and monitoring of deep foundation pit.
