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。 -
