1) precracking
预压裂
1.
Due to the cracks of cement stabilized base material which reflect to pavement under the load and become reflective cracks,the precracking technology is applied for treatment on semi-rigid base,which greatly reduces the amount and severity of shrinkage cracks.
由于水泥稳定基层材料产生收缩裂缝,在荷载作用下容易反射到路面,形成反射裂缝,采用半刚性基层预压裂技术对其进行处理,可以大大减少收缩裂缝的数量和严重程度。
2) prefabrication fracturing
预制式压裂
3) fracture effect forecast
压裂效果预测
1.
Test results illustrate its good practicability to solve oil well fracture effect forecast problem.
实际资料处理结果表明此网络模型对油井压裂效果预测问题具有良好的实用性。
4) Presplitting blasting with water pressure
水压预裂爆破
5) fracturing pressure prediction
