Abstract: The possibilities of using the earthwork of the dam as a highway are considered. The permissible loads on the earthen structure have been determined. Restrictions have been introduced for the operation of a certain type of motor transport.
Keywords: mobile load, slop stability, margin coefficient

  1. Introduction

When using dams as a road, it is necessary to ensure the required level of reliability in terms of strength, stability and deformability of the roadbed under the influence of established external and internal loads in accordance with [1].

According to [2], the impact of transport load on strength and stability is taken into account:

— in the form of an additional static load on the surface of the roadbed;

— additional dynamic impact arising, spreading and attenuating in the soils of the roadbed and its base, leading to a decrease in the calculated values of the strength and deformation properties of the soils.

Static normative and design characteristics of soils when assessing the reliability of the embankment are determined in accordance with the characteristics of the soils that make up the embankment body of the dam [3, 4].

When taking into account the dynamic impacts from vehicles in calculations of the strength, stability and deformability of the roadbed of a dam, on the crest of which a road is organized, standard loads and design loading schemes should be specified in accordance with [5, 6].

The article discusses the calculation method of the permissible load on the earthwork of the dam [7-9] using the example of the right-bank dam of the approach channel of the Novosibirsk lock. The technological passage of vehicles is located on the crest of the right-bank dam of the lower approach channel of the Novosibirsk lock. The schematic general plan of the lock is shown in Fig. 1.
