( 2 ) based on indoor test , two typical soft rock of brecciated mudstone and siltstone in luohu jiancheng district is carried systemically though interior rheological testing ; moreover combining with preceding studying results of rock rheological constitutive model , rheological numerical constitutive model suited to rock mass mechanics characteristics and stratum structure of luohu fracture zone , and numerical parameters of the model are processed with studying of curve fitting ( 2 )立足于室内试验，对罗湖建成区两种典型的软弱岩石?含角砾泥岩和粉砂岩进行系统的室内流变试验研究，又结合前人对岩石流变本构模型的研究成果，分析并确定了适合罗湖破碎带岩体力学特性及地层构造特征的流变计算本构模型，并对该模型的计算参数进行了曲线拟合研究。
The author suggests that the three lithosphere - scale faults , lancangjiang fault , jinshanjiang - ailaoshan fault and axis fault in the middle of the basin , are the main geological structures that control the formation of basin , magmatism and metallogenic congregate district . the anticline structure with an axis of triassic strata and the related fault system within the basin , and gonglang arch - shaped folding structure in the south of the basin are the geological structure controlling the formation of ore fields . junctions of two or more faults with different orientation , interlayer cataclastic structural zone and oxidation - reduction ( redox ) boundary were the favorable position for the formation of ore bodies 认为澜沧江断裂、金沙江-哀牢山断裂及盆地中轴断裂这三条岩石圈断裂是主要的控盆-控岩(岩浆岩)构造及矿集区尺度的控矿构造；盆地中以三叠系为轴的背斜构造及相关的断裂系统、盆地西南缘公郎弧形构造等是矿田尺度的控矿构造；多组断裂的交叉、层间破碎带及地层柱中的氧化还原界面是形成矿体的有利部位。
According to several engineering examples , this paper has probed and contrasted quantitatively the effect of chemical grouting . based on longyang canyon and lijia canyon , the author has concluded that chemical grouting attained satisfactory effect on strengthening fault so long as choose suitable grout ratio . based on wanjiazhai engineering ^ the author has assayed the cause that the effect was n ' t reasonable , that has the order before grouting and quantity during grouting etc . therefore , some reasonable proposals have been tabled in relations to the grouting methods and quantity methods 针对龙羊峡、李家峡两个工程实例的对比研究得到结论，只要选择合适的浆液配比，化学灌浆对断层破碎带的加固是可以取得令人满意的效果的；针对万家寨工程的研究，对其效果不理想的情况，分析了其出现的原因主要可能是由于其灌浆前处理进行的顺序及施工质量等，进而对以后的灌浆方法、施工方法等做一些合理化建议。
Alkali basite , which came from upper mantle or lower crust , invaded through those structure , which not only bring cu et al mineralizing elements , but also the most important is that thermal energy . it cycled the formation water ( yinmin fonnation and luoxue formation ) , and form alkali - rich , middle - high temperature and salinity fluid mixed with alkali - rich magmatic water . there were high rate of percolation and well voidage in the contact zone between yinmin purple stratum and yinmin rubblerocks , which is in favor of the transposition and mineralization of minerogenetic fluids 因此，总结东川稀矿山式铜矿成矿模式为沉积( fe 、 cu ) ?热液叠加( cu )改造：晋宁-澄江期，小江深大断裂发生走滑运动，在东川矿区造成右行旋扭及其派生构造，形成“ z ”字形落因破碎带，同时来自深源(下地壳或上地幔)碱基性岩浆侵入，不仅带来了大量cu等成矿物质，更重要的是提供了热源，促使地层水(落雪组白云岩和因民组紫色层)循环，与富碱( na和k )岩浆水混合，形成富碱中高温高盐度流体。
D ) the invasion of jinningian - chengjiangian alkali basite were unambiguous , the distribution of those rocks form " z " in shape , which similar with luoyin fracture zone and the distribution of copper deposit . it shows that copper deposits were controlled by discordogenic fault and its derived sub - structure , and there are relationship between copper deposit and jinningian - chengjiangian alkali basite . e ) most of minerogenetic age of copper deposit , which located in kunyang rift valley , belongs to jinningian - chengjiangian ( between 900 - 650ma ) , similar with the time limit of breaking - up of rodinia 东川矿区晋宁-澄江期碱基性岩侵入活动明显，常作为因民组复杂角砾岩胶结物和岩脉(体)产出，多分布于深大断裂及其派生的次级构造附近，明显受南北向小江深大断裂走滑运动引起的右行旋扭及其派生构造控制，与“落因破碎带”和“铜矿分布”较吻合，均为“ z ”字形。
