The design and calculation of support structure of deep foundation ditch is analysed. It is required in engineering to design the support structure of deep foundation ditch reasonably. There are many methods to design the support structure of deep foundation ditch. Every one has its advantages and disadvantages. Segmented equivalent beam method is a simple calculating method. The procedure of construction is considered in the computer method. Calculating results accord with the fact. It is adopted extensively in engineering, but in designing,a higher equation is solved. It is easer to design by MathCAD system. The design and calculation of multi-point support structure of deep foundation ditch is described by adopting the MathCAD. A quick and reasoned design and calculation method has been advanced for the design and construction unit to design and construct the support structure of deep foundation ditch safely and suitably.
