中文摘要:
      在某高速公路采空区优化治理与质量检测研究课题中首次采用三维渗流方程对采空区冒落带、裂隙带的注浆过程进行了数值模拟,其结果令人满意。根据设计的注浆压力和地层条件,利用数值模型来求得注浆量及注浆半径(包括冒落带和裂隙带),为优化设计提供依据。
英文摘要:
      In a research topic of abandoned workings optimizing control and quality de tection under an expressway, we use the 3D s eepage flow equation on nimerical analog of grouting process in caving zone and fractu red zone upon abandoned workings for the fi rst time, and the result is all that could be desired. According to designed grouting pr essure and geological condition, to use num erical model applies for slurry capacity an d grouting radius (including both caving zo ne and fractured zone), thus provide a basis for optimized designs.
