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。
