A fitting function of lateral displacement of cemented soil retaining wall was proposed according to several measured data of excavations. On this basis, the retaining wall was treated as a homogeneous elastic vertical beam, whose toe and heel were restricted by a spring constraint but still could be moved and rotated. An analytical formula of the lateral displacement of the retaining wall was deduced with the principle of minimum potential energy with consideration of all the external forces. Compared with some other measured data, the average relative error of the formula was less than 10%, which preliminary indicated the formula's practical value.
