综合物探检测在龙溪口航电枢纽工程建基面岩体检测中的应用

为保证岷江龙溪口航电枢纽工程施工质量，做好岩体质量检测具有重要意义。采用钻孔声波、钻孔全景图像及钻孔变形模量测试等物探检测手段在建基面开挖过程中对基础岩体进行物探测试，揭示了坝基岩体波速分布、裂隙发育及变形模量等信息，为确定最终建基面高程提供了数据依据，对节约工程投资和工期具有积极意义。

Application of comprehensive geophysical detection in bedrock detection of Longxikou Navigation-power Junction project

To ensure the construction quality of the Longxikou Navigation-power Junction project in Minjiang River,it is of great significance to well detect bedrock quality.This paper adopts geophysical detection methods such as drilling sound waves,drilling panoramic images,and borehole deformation modulus tests to conduct geophysical testing of the bedrock during the excavation of the foundation surface.The paper reveals the wave velocity distribution,fracture development,and deformation modulus of the dam bedrock,which provides a data basis for determining the final foundation surface elevation and has positive significance for saving project investment and construction period.
