摘要：The sheet pile wall (SPW) is carried out from pipes of big diameter which plunge into soil very deeply. Depth of pipes is the settlement size depending on a set of parameters. Depth of pipes provides rigidity and reliability of a construction. SPW has a high rate of a consumption of steel on his production. Authors of the present article suggest to reduce a material capacity of SPW at the expense of reduction of depth of blockage of every second pipe. Decrease in depth of blockage of separate pipes is carried out at preservation of the maximum depth of blockage of other pipes. The design similar to a «comb» because of alternation of long and short pipes turns out. Such decision allows to reduce the total depth of blockage of pipes and as a result leads to decrease in a material capacity and cost of a construction in general. The problem of search of possible reduction of length of a part of pipes is the purpose of the real research. As solutions of the put problem we suggest to execute numerical experimenting in iterative statement with use of modern software. Results of numerical researches of SPW are presented in the present article. The presented results allow to draw a conclusion on efficiency of the solution on decrease in a material capacity of SPW proposed by authors. For obtaining the generalized decision and obtaining undoubtedly the best result of a design of SPW authors consider necessary to execute problem definition in the form of parametrical optimization.
