根據其中的疊層石和無明顯泥裂構造，推測為潮間帶局限潮下帶沉積環境。The study solves engineering problem as follows : ( 1 ) the systematic study on the historical course of xigeda strata deposit and geologic environment includes strata, lithologic characters and constitution et in the liangshan and panzhihua region. the results show that the xichang - panzhihua express way is controlled by the anninghe fault and the xigeda fault, the earthquake frequently happen in the region of pass, the different sedimentation number is more great, they effect the road building, safety in operation and structure belong road ( 2 ) because in some place the xigeda strata is foundation and roadbed, the study on the basic properties of the xigeda strata include density, moisture content plastic and liquid limit graduation. the results show that the xigeda strata is deposition in lake, the main component is mudstone and sandstone, the fine particle is main, it has some viscosity, the moisture content of mudstone is different the it of sandstone, the other property are likeness. the xigeda strata has no dilatation on total, some claystone have low and medium dilatation ; ( 3 ) the study on the basic properties of xigeda filler include the composition of matter the biggest standard dry density, the optimum moisture content the results show that xigeda filler can use as road material, it is well grade filler and admixture filler on essence, its compaction index should change in different place because the property is controlled by mudstone and sandstone that change is great in different place ; ( 4 ) the study on the xigeda filler craft used as express way roadbed, includes suitable thickness, compaction numbers and methods and equipment choice et
公路沿線廣泛分佈有昔格達地層，昔格達地層能否用作高速公路路基填料，國內沒有先例，本論文就是結合導師的科研項目，在非典期間，現場長達5個月的工作，完成了從試驗、現場施工工藝到路堤分層沉降監測等工作，是面對生產實際，認識昔格達地層的性質和其作為地基、路基和填料應用中面臨的問題進行的研究。主要的研究內容有：對攀西地區地層巖性、構造等地質環境和昔格達地層的沉積歷史過程作了系統的分析，研究表明西攀高速公路主要受安寧河斷裂和昔格達斷裂影響，通過地區地震活動頻繁，差異沉降較大，對公路建設、安全運行和沿線構築物設計有較大影響；由於昔格達地層在有些路段作為地基、有些作為路基，對其基本性質進行了研究：包括天然密度、含水量、塑液限、顆粒級配等指標的試驗研究。研究成果表明：昔格達地層為湖相沉積，主要為砂巖和泥巖，它以細粒組為主，同時粘粒的存在，使其具有一定粘性。This is the direct reason of bad reservoir property of sandstone, especially lower permeability. the influence and control factors of reservoirs include : deposition, diagenesis and tectogenesis. the deposition is the basic factor, it control the shape and distribution of sand body, and influence the type and the intensity of the diagenesis ; the diagenesis is the key factor, it control the process of pore evolvement, so the diagenesis control the sandstone ' s storage space and reservoir quality directly ; the fracture of the tectogenesis formation could improve the porosity and permeability of sandstone
其中沉積作用是基礎，控制了儲集砂體的形態特徵和分佈范圍，同時由於不同沉積類型砂體在碎屑成分組成、泥質含量、顆粒粒度、砂體厚度、砂體內部的非均質性、孔隙介質的物理化學性質等方面不盡相同，從而也影響著砂巖所經歷的成巖作用路徑、類型和強度，因此沉積作用是控制儲層發育的主導因素；成巖作用是關鍵，直接決定了砂巖的孔隙演化過程，從而決定了儲層內部儲集空間特徵和儲集性能；而構造作用形成的裂縫對改善砂巖的儲滲性能具有一定作用。Therefore, the present paper, based on the existing achievements as well as an extensive study & investigation in combination with part of the achievements the author has derived by hosting or participating in the research programs of the cement concrete pavement, has led to three phases of fissures and breaking in the pavement slab on the condition that each performance of the subgrade is maintained, i. e. stages of formation in initial cracks, of accumulation & expansion in ruptures and of fissures & breakage in the pavement
為此，本文在已有研究成果的基礎上通過廣泛調研，結合作者近幾年來主持或參加的有關水泥混凝土路面研究課題的部分成果，在路面基層的各種性能得到保障的前提下，通過理論研究和試驗研究，得出路面板的開裂破壞過程分為三個階段，即初始裂縫形成階段、裂縫累積和擴展階段以及路面斷裂破壞階段。分享友人
