Abstract : this article touches on the advantages of using steel - core belt conveying system in the conditions of large transportation quantity , big obliquity , longer distance and complicated geology 文摘:通过实例阐述钢绳芯胶带运输在大运量、大倾角、长距离、复杂地质条件下使用的优越性。
The calculation results by the method do n ' t always conform to the facts , since the rigid body assumption and the assumed direction of inactive forces between slices in this method . furthermore , it is difficult to analyze 3d slope with limit equilibrium method , considered the complexity of geologic structure 常用的边坡稳定分析方法中的极限平衡法由于采用了刚体假定以及块体间力的传递方向假定等，使得计算结果与实际出入较大且用于含有复杂地质条件的三维边坡问题非常困难。
During the construction of concrete cut - off wall of the auxiliary dam in huangbizhuang reservoir , in the section with complex geographical condition , especially the closure section of concrete cut - off wall ( about 120m ) , the deterioration of the underground water ' s flow state and the existence of the overseep channel in the stratum result in the several collapses in the dam crest . through the analysis of ever } 1 collapse ' s reason , the proposal of handling measure and its effect , the paper expounds and proves that the cut - off wall can be safely constructed and devoted into normal usage after dealing with collapse . the psper improves the construction technique and method of concrete cut - off wall especially under complex geological condition and in the overseep stratum 本文通过对历次塌坑的原因分析及历次塌坑处理措施的提出和对历次塌坑处理效果的分析，论证了塌坑处理后防渗墙能安全施工和投入正常运用；完善了在复杂地质条件及强渗漏地层混凝土防渗墙的施工工艺和施工方法；提出了对病险水库加固及在地质条件复杂地层中修建混凝土防渗墙的施工要点；同时提出了在强渗漏地层修建防渗墙的关键是在防渗墙施工前通过预注浆封闭强渗漏通道的重要论点；对塌坑一些处理措施中的不足之处亦进行了分析研究，供国内类似工程借鉴。
As the oil exploration aimed at anisotropy inhomogeneous porous reservoir presently , it is important to study the acoustic theory and borehole acoustic field distribution with numerical simulating so as to invent new logging methods and equipments to obtain enough information to evaluate the complex reservoir characters quantificationally and identify the hydrocarbon zone accurately 随著陆上油气勘探目标趋向孔隙结构复杂、非均质性强的油气储集层，基于地层各向同性介质的测井理论显露弊端；因此研究复杂地质条件下的井筒声场分布特徵、为储层解释和发展刚井新方法提供理论依据成为必然。
In the process of work , according to complex geological conditions such as huge thick soft clay in site and top surface of possible pile foundation supporting course fluctuating in large amplitude , we adopted many advanced exploratory methods ( just as high accuracy exploration of shallow earthquake , crosshole wave velocity test , vane shear test , pressuremeter test , etc . ) , we found out that there is an ancient groove of yangzi river in former plant site , therefore we suggested in time that plant site should properly be moved eastwardly , only this item saved nearly about 50 million for pile foundation project cost 在工作过程，根据厂址区软粘土厚度大、可能作为桩基持力层顶面起伏变化大等复杂地质条件，采取了多种先进的勘探手段（如高精度浅层地震勘探、跨孔波速试验、十字板剪切试验、旁压试验等） ，查明了原厂址区存在一个长江古凹槽，并及时建议厂址适当东移，仅次一项就节省桩基工程费用近5000万元。
