高密度地震映像在道路沉陷探测中的应用
|
摘要
针对基坑透水引发的道路及基础沉降问题,采用地震映像技术对隐患区地下土层变化进行了检测。较准确地查明了测区内地下土层受透水影响而导致的空洞异常和明显沉陷异常,总结了上述异常的判别标准,为沉降区后期道路加固修护提供了科学依据,并可为类似工程处理提供借鉴。
This paper for the Pit permeable caused by road and foundation settlement problem uses seismic imaging technology to detect the hidden underground soil changes.The underground soil cavity abnormalities and the apparent subsidence anomaly of the survey area caused by permeable are accurately identified,and the above unusual criterion is summarized,which provides a scientific basis for the late road reinforcement repair of the settlement of the area and provides a reference for the similar engineering processing.
