Hello,
The numerical simulation adopts the three-field coupling method of temperature field, structure field and seepage field.
After the first stage of grouting enters the foundation, the grout will undergo a phase change, forming a composite soil with part of the foundation (not all), and the physical and mechanical properties of the composite foundation (such as permeability, elastic modulus, strength, etc.) will change;The second stage of grouting is carried out on the basis of changes in the ground properties. Due to the changes in the properties of the composite soil, the second stage of grouting may damage the composite soil.
How can this situation be achieved?
PS. The biggest problem at present is: how to update the properties of the composite soil before the second grouting starts？
Thanks
