laboratory tests

Problems and insufficient research of the issue of reinforcement of soil-cement piles are revealed. The use of fiber for reinforcing piles made by the deep soil mixing method is proposed. As a result, it is expected to increase the strength of soil cement, which will positively affect the bearing capacity of soil-cement piles on the material. Given the advantages for applications in the studies adopted steel fiber. The program of tests with the application of two-factor matrices of planning of experiment is made.

This paper is devoted to the comparison of four yield criteria used for reinforced concrete plates with the amount of reinforcement not exceeding the balanced reinforcement. The basis of the assessment was the conformity of theoretical results with experimental results of tests on some series of slabs subjected to a homogeneous moment field load.
