强夯处理深垃圾坑作为道路路基的应用

Application of Deep Rubbish Pit Treated by Dynamic Compaction Method as Roadbed

对深垃圾坑进行强夯作为道路路基是解决建筑垃圾与日俱增的有效措施。通过采用强夯桩式置换的方式,对西康铁路两侧垃圾填埋段进行处理,并对处理后的地基承载力、沉降观测及回弹模量进行了现场试验,结果表明该方法处理的路基能够满足设计要求。同时对施工过程中技术参数的选用、施工要求以及注意事项提出了建议。希望给强夯处理深垃圾坑作为道路路基提供些参考意见。

The deep rubbish pit treated by the dynamic compaction method as roadbed is the efficient measures to solve the increment of building rubbish. The rubbish backfill sections at the both sides of Xikang Railway are treated by the dynamic compaction pile replacement mode. The field test is carried out for the treated ground bearing capacity, settlement observation and resilient modulus. The result shows that the roadbed treated by this method can satisfy the design requirement. The article puts forward the proposals for the selection of technical parameters, the requirement of construction and the matters for attention in the construction process, which can be referred for the deep rubbish pit treated by dynamic compaction method as roadbed.
