“…Its diameter can reach up to 1.2 m. To prevent the borehole from collapsing, it is welded with a metal short pipe. When the boreholes are drilled in clay soils, the walls of the hole are smooth, with a clay layer forming on the walls, which strengthens and prevents landslides before the installation of concrete [3,4].…”

The work refers to the modern method of stabilizing unstable, water-saturated creeping slopes, with the combination of bulk piles and gabions. The application of the method makes it possible to ensure the stability of the slope by means of bulk piles, passing through weak soils, building semi-massive gabion walls on the piles with a stepped front edge. Bulk piles and gabions are used in modern construction for strengthening the slopes of river banks, in the preparation of protective structures to stand the rockfall, avalanche floods, in the construction of bridges, hydraulic and other facilities. The novelty of the proposed method is the stabilization and watering of the slopes organized without the construction of reinforced concrete retaining walls and land-based systems. It provides strength in depth and minimizing hydrostatic pressure.

“…At present, pile foundation is the most commonly used foundation form in highway bridge construction, and it is a durable and effective infrastructure [11][12][13][14][15]. In the loess region of Shaanxi Province, bored cast-in-place piles are widely used due to their well-developed construction technology and high bearing capacity [16][17][18][19][20][21]. Most of the piles are 30-70 m in length and more than 1 m in diameter.…”

In this paper, a static load test and a multiparameter statistical analysis method are used to study the value of pile side friction in different soil layers in a loess region. Currently, static load testing is the most commonly used method to determine the bearing capacity of pile foundation. During the test, a vertical load is applied at the top of the pile, the data under each load level are recorded, and a Q-S curve is drawn to obtain the ultimate bearing capacity of a single pile. Reinforcement stress gauges are installed at different sections of the pile body, and then the axial force and the pile side friction of each section are calculated. Few studies have investigated the calculation of pile side friction in different soil layers using the multiparameter statistical analysis method. Obtaining accurate results using this method will provide an important supplement to the calculation of pile side friction and will also be conducive to the development of theoretical calculation of pile side friction. Therefore, taking Wuding Expressway project in loess region as an example, the lateral friction resistance of six test piles is studied through static load testing and multiparameter statistical analysis. The multiparameter statistical analysis method is compared with the static load test results, and the error is controlled within 20%. The results show that the calculation results of multiparameter statistical analysis essentially fulfill engineering requirements.
