密实指数
Examples
- Application and comparison of soil compaction indexes in the evaluation of urban soils
土壤压实指标在城市土壤评价中的应用与比较 - 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
公路沿线广泛分布有昔格达地层，昔格达地层能否用作高速公路路基填料，国内没有先例，本论文就是结合导师的科研项目，在非典期间，现场长达5个月的工作，完成了从试验、现场施工工艺到路堤分层沉降监测等工作，是面对生产实际，认识昔格达地层的性质和其作为地基、路基和填料应用中面临的问题进行的研究。主要的研究内容有：对攀西地区地层岩性、构造等地质环境和昔格达地层的沉积历史过程作了系统的分析，研究表明西攀高速公路主要受安宁河断裂和昔格达断裂影响，通过地区地震活动频繁，差异沉降较大，对公路建设、安全运行和沿线构筑物设计有较大影响；由于昔格达地层在有些路段作为地基、有些作为路基，对其基本性质进行了研究：包括天然密度、含水量、塑液限、颗粒级配等指标的试验研究。研究成果表明：昔格达地层为湖相沉积，主要为砂岩和泥岩，它以细粒组为主，同时粘粒的存在，使其具有一定粘性。
