土的冲击压实原理及其在高级公路路基压实度控制中的应用效果

Impact Compaction Principles of Soil and Its Application Effect in Controlling of Compaction Degree of Highway Roadbed

分析了冲击压实技术原理、优势以及冲击压实技术特点和施工步骤。通过工程试验,重点分析了路基冲击压实技术在施工中的重要作用。利用冲击压实技术处理路基,可以进一步保证路基填土压实度指标的控制,减少路基工后沉降。冲击压实施工效率高、压实速度快,影响深度大,可填土厚度大,施工速度快。

This paper analyzes the principles, advantages, characteristics and construction procedures of impact compaction technique. By the engineering test, it emphatically anayzes its important contribution to roadbed construction. Making the use of impact compaction technique to treat roadbed can assure the degree of compaction of roadbed banquette further, and reduce the sedimentation of roadbed. When impact compaction technique is adopted, the construction efficiency is high, compaction speed is rapid, affection depth is deep, thickness of banquestte is big, and construction speed is quick.
