Which of the following statements regarding the graphical representation methods and basic rules for fundamental graphs is incorrect? ( ) A. The grid of alignment axes in the foundation plan is exactly the same as that in the building plan. B. In the foundation plan, only the contour lines of the foundation walls, columns, and the base surface of the foundation are drawn; the detailed contours of the foundation can be omitted. C. The dimensioning in a foundation plan includes external dimensions, internal dimensions, and detailed dimensions. D. When a composite foundation is used, it is necessary to show the range and depth of the composite foundation treatment, as well as the plan layout of the replacement piles, along with their material and performance requirements and structural details. Answer: C 【Explanation】In a foundation plan, only the contour lines of the foundation walls, columns, and the base surface of the foundation are drawn; the detailed contours of the foundation, such as those related to the base plates, can be omitted. The positioning axis grid in the base plan is exactly the same as the axis grid in the building plan. The dimensioning of the basic floor plan is divided into external dimensions and internal dimensions. When a composite foundation is used, the treatment area and depth of the composite foundation should be indicated, as well as the plan layout of the replacement piles, their material and performance requirements, and the detailed construction specifications ； Specify relevant parameters such as the bearing capacity characteristic value and deformation control value of the composite foundation, as well as the inspection requirements.
