1) prefabrication fracturing
预制式压裂
2) pressure precast pile-stinking
静压式预制桩
3) 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。
4) controlled blasting
控制预裂
1.
Effects of controlled blasting and pre-splitting blasting on latter blasting holes;
控制预裂和后爆孔的空孔作用
5) pre-existing crack

Experiments were carried out to study coarse marble with discontinuous pre-existing cracks under conventional triaxial compression by the MTS815.
03岩石力学伺服试验机上对断续预制裂纹粗晶大理岩进行常规三轴压缩试验,基于试验结果研究不同围压下断续预制裂纹粗晶大理岩的变形和强度特性。
2.
Rock Failure Process Analysis(RFPA) code is used to study the failure process of rock disks with pre-existing cracks under dynamic loading.
本文利用岩石破裂过程分析系统(RFPA)研究了含有不同角度预制裂纹的岩石试样在动态载荷作用下的破坏过程。
3.
Rock failure process analysis (RFPA) code is used to study the failure process of rock disks with pre-existing cracks when subjected to static loading.
数值模拟再现了含不同预制裂纹角度时巴西盘试样所表现出不同的破裂模式以及主裂纹的产生、扩展、贯通、次生裂纹的产生等过程,得到的破裂模式结果与有关文献中的实验结果十分吻合。
6) Crack preparation
裂纹预制
1.
Crack preparation and characterization of Al_2O_3-MgAlON composite sintered under normal pressure;
研究了裂纹预制方法、试样的粒度组成以及获得维氏压痕时的载荷大小和保压时间对裂纹形状和尺寸的影响,愈合温度对压痕愈合情况及试样抗折强度的影响,并计算了维氏压痕的愈合速率。
