ACOUSTICS CHARACTERISTICS OF DEEP CEMENT AGITATING PILE AND MEASUREMENT OF STRESS WAVE REFLECTION
水泥深层搅拌桩声学性质与应力波反射法测试

The characteristics of acoustics and strength of deep cement agitating pile are studied and they depend on the physical and mechanical properties of cement and soil. Some relative formulas are given based on the experiments. The measurement method of stress wave reflection used for quality evaluation on cement pile is discussed after analysis on theoretical feasibility and practical maneuverability.
