摘　　要：对于重力式码头,改造施工前需对前沿基床进行详细检测,明确基床底标高及淤积状态。为解决码头前沿小范围内基床标高测量难的问题,结合工程实例,对基于轻型动力触探技术基床检测方法进行了阐述,并采用淤泥开挖冲排的方式对测量偏差进行了验证,结果表明采用轻型动力触探技术进行基床标高的检测数据是可信可靠的,成果可以为码头基床检测提供参考借鉴。For gravity wharf, the front bedding should be tested in detail before the reconstruction, and the bottom elevation and siltation state of the foundation bed should be defined. In order to solve the small scope of the quay in bed elevation surveying problems, combined with the engineering example, bed testing based on light dynamic penetration test was described, and the way to discharge the silt excavation measurement deviation was verified, results show that the detection data of bed elevation and silt depth by light dynamic penetration test is reliable. The results can provide reference for wharf bed detection.
