软土地基勘察中静力触探与标准贯入试验对比分析

Key Points

• The aim is to analyze the differences between CPT and SPT methods in soft soil foundation investigations.
• Describes the principles and technical features of CPT and SPT.
• Compares testing mechanisms, data continuity, and parameter acquisition capabilities across both methods.
• Proposes a complementary investigation strategy using CPT primarily and SPT secondarily.
• CPT shows better performance in precise soil layer classification due to its continuous and high-resolution data.
• SPT is limited in soft soils but provides irreplaceable value through disturbed soil sampling and existing engineering experience.
• A comprehensive investigation strategy is proposed, validated by examples.
