主要的环境地质问题是：活动性断裂、地震带的地壳不稳定；崩塌、滑坡、泥石流及水土流失；地下岩溶塌陷、渗漏问题；基础岩体膨胀、胀缩土体、含盐层侵蚀变形和地下水的腐蚀危害；盆地软土问题；软弱岩体、碎裂、风化岩体稳定性较差；高寒地带公路、铁路建设的冻土冻融灾害问题；煤层瓦斯、涌水、地下采空区等隧道围岩不稳定问题；工程切坡、施工弃土及水库、湖泊生态地质环境保护问题；航道险滩、暗礁问题；渠化工程、码头等库岸再造问题；以及机场建设中的不稳定地基及地下水腐蚀性问题；同时，随着大通道建设的实施和完成，城镇建设的调整、人群居落的变化和耕地分布及结构的调整组合，都可能造成局部环境地质问题的突出等等。经多元统计分析数值计算、综合评价结果，滇西北、滇西南地区交通密度较低，交通工程对环境的影响程度较弱，是环境地质状况好的区域；有主要高原湖泊分布区的，包括昆明、个旧、文山的滇东南区域，环境地质状况较好；大姚、楚雄、篙明及会泽、昭通一镇雄的区域，即滇中北部中生界红层和滇东北岩溶区，环境地质状况中等；而包括保山、德宏、大理、临沧的滇西地区及景东一墨江以东、双柏一石屏一河口以西及东川一寻甸一曲靖地段的滇中一滇东地区，环境地质状况较差。云南国际大通道建设涉及全省区域，如何利用地质环境、实现可持续发展，就必须依赖于国际大通道建设与地质环境之间良性关系的建立。应本着对区域地质环境客观存在的科学认识原则、建设过程中环境效益优先的可持续发展原则、法制性原则、对大通道建设中环境地质的因地制宜及其可防治性原则。并且从组织管理、不同类型大通道、不同环境地质问题类型等方面，提出了对策措施。最后，提出了建立国际大通道建设与环境地质良性关系的宏观建议。

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on.
