武汉马影河流域典型耦合地质体及工程特征初探

Preliminary Study on Typical Coupling Geological and Engineering Characteristics of Maying River Basin in Wuhan

超深、超大、超长工程的建设,既需要面临岩、土、水的风险考验,也必须考虑岩土地质体与工程建设之间的相互作用。为了满足工程建设的安全、质量、环保、可持续发展的要求,需要从岩、土、水等耦合地质体的角度去分析其特征及其对工程的不利影响。该文从工程应用角度出发,探讨性的提出耦合地质体概念及相关分类方式,以武汉马影河流域为例,梳理出“深厚填土+软土”、“软土+互层土”、“软土+岩溶”、“砂土+岩溶”四类比较典型的耦合地质体类型,并结合研究区具体工程实例,剖析典型耦合地质体的相关特征与工程不良效应等,为后期开展相关工作提供一定的借鉴。

The construction of super deep,super large and super long projects not only needs to face rock,soil and water risks,but also must consider the interaction between rock and soil mass and project construction.In order to meet the requirements of safety,quality,environmental protection and sustainable development of engineering construction,it is necessary to analyze its characteristics and adverse effects on the project from the perspective of coupling geological bodies such as rock,soil and water.From the perspective of engineering application,this paper puts forward the concept of coupling geological and relevant classification methods.Taking the Maying River basin in Wuhan as an example,four typical types of coupling geological bodies are sorted out,namely,“deep fill+soft soil”,“soft soil+interbedded soil”,“soft soil+karst”and“sand+karst”.Combined with specific engineering examples in the study area,the relevant characteristics and adverse effects of typical coupling geological are analyzed.It provides some references for later related work.
