公路工程石方路堑的爆破施工技术

The Blasting Construction Technology in the Stone Cutting of Highway Engineering

通过002线K7+220～K7+370段路堑全断面一次性爆破成型的施工实践,总结了深孔微差松动爆破和预裂爆破相结合施工的参数设计、网络设计等路堑爆破的施工经验。

Through the construction practice of the whole section one-time blasting molding in the of KT＋220-KT＋370 section cutting of 002 line, this paper sums up the construction experiments of stone cutting blasting on the parameter design and network design of the construction combining the deep-hope millisecond loose blasting with the pre-splitting blasting.
