• Abstract: the geological conditions of South China fold belt are relatively complex, bedrock fissures are relatively developed, and the geological conditions of the same bearing stratum of pile foundation will change obviously before and after construction. Taking Cangjiang bridge in Gaoming District of Foshan City as an example, this paper makes a deep analysis of this phenomenon, and briefly introduces the construction technology of high strain detection, which has a certain reference for pile foundation detection in the same area. 华南褶皱带地质条件较为复杂，基岩裂隙比较发育，同一桩基持力层地质情况在施工前后会发生较为明显的变化。以佛山市高明区沧江桥为例，对这种现象进行了深入分析，并简要介绍了高应变检测施工工艺，对同类地区桩基检测具有一定参考作用。
