某厂房为河床式厂房,位于坝址右岸,基岩为泥质粉砂岩、粉砂质泥岩,饱和抗压强度6～15KPa,属软岩。施工过程中通过采用控制爆破技术,达到了边坡预裂面完整、基础建基面平整的效果,有效保证了开挖边坡的稳定和被保留岩体的完整性。
A plant for the river bed plant, located on the right bank dam site, bedrock muddy siltstone, silty mudstone, saturated compressive strength of 6 ~ 15KPa, is a soft rock. Through the use of controlled blasting technology in the construction process, the pre-cracking surface of the slope is completed and the foundation surface is smooth. The stability of the excavation slope and the integrity of the retained rock mass are effectively ensured.
