碎石注浆桩在高速公路软基加固中的工程实践

Working practice of crushed-stone-mortar-pile in expressway soft-soil reinforcement

本文以工程实际为例,介绍了碎石注浆桩在软土地基加固中的应用。工程实践表明该技术经济合理,技术可行,效果明显。鉴于目前碎石注浆桩加固软基技术尚无国家和行业标准,介绍其施工技术与控制标准以供商榷。

Taking practical work as an example,the application of crushed-stone-cast-pile in soft-soil reinforcement was introduced.Working practice shows clearly that this method is economically reasonable and technically feasible with tangible results.As now there is no national or industry standard for this technique of crushed-stone-cast-pile in soft-soil reiforcement,its construction method and controlling standard is described here for discussion.
