“…When constructing a highway in water-rich soft soil areas, specific countermeasures need to be taken to improve the strength and deformation behavior of the ground. As an effective ground improvement alternative, the composite foundation technique has been widely applied for constructing various infrastructures, such as railways, ports, and highway subgrades [1][2][3][4][5]. In water-rich flood plains, the soft soil within the ground exhibits unsatisfactory engineering properties, including high compressibility, low bearing capacity, etc.…”

The settlement behavior of composite foundations plays an important role in the serviceability and stability of the subgrade or other infrastructures supporting the foundation. However, in water-rich flood plains, due to the complexity of the soft soil properties, the settlement behavior has not been well understood. The objective of this study is to investigate the effects of various key factors on the settlement behavior of composite foundations with deep mixed piles supporting highway subgrade in water-rich flood plains. The investigated subgrade is in operation, and the vehicle load is taken into account. The G347AH Project is considered in this study. Several typical models for predicting composite foundation settlements are discussed. By performing three-dimensional finite difference analysis, a comparison is made between the settlement behavior of the natural foundation and the composite foundation with deep mixed piles. Based on the single factor sensitivity analysis and the multi-factor orthogonal experimental design, the effects of pile length, pile diameter, pile spacing, pile elasticity modulus, cushion elasticity modulus, and cushion thickness on the composite foundation settlement are captured. It is found that among these factors, the degree of influence of pile length is superior. The composite foundation settlements predicted by the models agree well with the field-monitoring data, with the error being about 8.42% and 6.38%, respectively, at two monitoring sections. The research conducted in this paper can effectively reduce the probability of various settlement-related disasters occurring on highway subgrades in water-rich flood plains. Moreover, the research has important theoretical guidance for design optimization in terms of settlement control of highway subgrades in soft soil areas.

This paper presents a direct calculation of the average value of defective elements of point products. Production process control is considered using the example of the control of point products. The calculation of the first four moments in a binomial distribution of the number of defective elements of point products is made. The standard error of the fraction of defective elements is considered in detail.

Statistical methods of control of point components and quality of point products are an integral part of modern point production, and their application is closely connected with solving tasks of increasing labour productivity and general enterprise culture, saving materials, and reducing defects. The paper presents a derivation of basic formulas for a binomial distribution of elements of the railway track superstructure. Calculation of theoretical distribution is made. The interrelation between probability theory, statistics, and quality control of point products is considered.
