| 4. | Paleomagnetists , who study the effect of the magnetic field in the geologic record , discovered this phenomenon while studying the crystalline structure of rocks
古磁学家在地质的记录方面研究磁场作用,在研究岩石的水晶的结构时发现了这一现象。 |
| 5. | The rule of destruction and deformation is controlled by the structure of rock mass , and the deformation and destruction of rock mass cannot be decided by the criteria of general materials
其破坏规律很大程度上受岩体结构制约。同样，其变形也受岩体结构控制，其变形和破坏不能简单地用一般材料的变形规律和失稳判据来判断。 |
| 6. | Numerous examples of rock mass engineering indicate that the deformation and breaking law of rock mass depends on its structural characteristics and the stability of rock mass construction is controlled by the very structure of rock mass
大量的岩体工程实例表明：岩体的变形和破坏规律取决于岩体的结构特性，岩体工程的稳定状态受岩体自身结构控制。 |
| 7. | In riverbed , rqd is an appropriate index of rock mass structure classification . because the weathering agent causes the change of integrity and structure of rock mass , the relationship between rock mass structure indexes and weathering zoning is discussed through wave velocity ratio
风化营力的作用使岩体中次生裂隙增多从而导致岩体完整性、岩体结构的变化，本文以波速比为纽带，研究了两岸坝肩部位岩体结构量化指标与风化分带的关系。 |
| 8. | Based on the simplified structure of rock mass , three - dimensional finite element numerical modeling technique is used to analyze systematically the distribution features of filed , strain field and plastic zone in the surrounding rock mass of the underground cavities after the excavation
在岩体结构模型概化的基础上，采有三维有限元数值分析方法，系统研究了大跨度、高边墙地下洞室群开挖完成后围岩的二次应力场、变形场和塑性破坏区的变化特征。 |
| 9. | The mechanical genesis of the complicated rock mass is because several times of tectonism in pro - period made the structure of rock mass in the right dam foundation damaged seriously and rock mass alteration made its mechanical character more anisotropy . after that the fractures in the right dam foundation slope were stretched at the beginning of the quaternary period because in the period yakouhoushan mountain quaquaversal dome was blowups quickly . at the same time , the valley trenching of lancang river reach to 800 - 1000 meter in altitude at the right bank in nuozadu dam site
导致右岸岩体复杂化的成因是，右岸岩体在早期遭受了多期构造作用和岩体蚀变的基础上，第四纪早期丫口后山穹隆的快速隆起与当时河谷下切至800m 1000m高程这一特殊因素组合引起了右岸岩体沿原有的断裂(裂隙)张开，使地下水等风化营力能够到达坡体较深部位，经过长期的风化卸荷作用，形成了右岸复杂岩体。 |
| 10. | In recent years , the carst collapses that are occurring frequently in qixiashan hill area severely endanger the engineer and human life . there are many factors caused the occurring of the carst collapse in this area . besides the background of geology and geomorphology , the causes of changing of hydrodynamic , stress field of the earth s crust , and structure of rock and ground are more important
近年来，南京栖霞山地区岩溶地面塌陷频繁发生，造成了巨大的经济损失。岩溶地面塌陷的产生，除了地质地貌基础外，更主要原因在于矿山开采改变了水动力条件地应力场及岩土体结构，尤其是矿坑疏干对水动力条件的影响最为显著。 |
