Purpose This paper aims to first analyze the reasons of a brick-wooden building tilts in Yunnan province in China. Then, a jacking method which combines the stress release methods and the excavation of stress release trench were put forward. Design/methodology/approach This method uses the anchor static pile to guarantee the safety of the building in the process of rectifying. Findings The practice showed that the inclination rate of the building was stable in the process of jacking, which proved the efficiency of the proposed method. Originality/value It has a great value for similar rectification projects, and for the protection of cultural heritage and ancient buildings have a positive effect.

Ethiopia is almost mountainous and hilly in topography, with many rivers flowing from the cities' centers. To facilitate transportation, a bridge across the Berbere Wonze River must be built. The bearing capacity of foundation soil is important for foundation design because it can carry heavy loads from the superstructure. The primary goal of this experimental geotechnical investigation is to determine the bearing capacity of foundation soil for the design of bridge foundation at Berbere Wonze River in Amahara Region South Wollo, Kombolcha, Ethiopia. The foundation investigation work includes a Dynamic Cone Penetration (DCP) test, a Standard Penetration Test (SPT), visual identification, groundwater monitoring, soil sampling, and subsequent laboratory tests on representative samples to determine the physical and engineering properties of the subsurface formations and soil underlying the proposed bridge sites. These are to provide safe and cost-effective foundations based on a combination of field data and laboratory test results.

“…Akpila and Omunguye [4] performed laboratory tests and analyses to study the influence of foundation settlement on the adoption of an appropriate applied pressure of a shallow footing found on sandy clay soil. In general, the allowable load capacity of footing changes from 73 -86 kN/m 2 for raft width equal 19.3 to 29.5 m up to 3 m levels below ground surface, it was observed that settlement consideration affect the value of bearing capacity needed for the foundation analysis and design in a sandy clay soil.…”

In the present study, laboratory model tests and numerical analysis are carried out to study the immediate, and consolidation settlement of shallow foundations rested on clayey soil. The purpose is to evaluate the immediate and consolidation settlement of different cases and compares them with the calculated values using theoretical equations; the numerical analysis is utilized by the Plaxis-3D program for developing the finite element model, whereas the soft soil model was used for simulation. It was studied the effect of three parameters on the behavior of the foundation for immediate and consolidation settlement, these parameters are soil cohesion, the pressure applied on the foundation, and layer thickness. The obtained results indicated that the simulation using the soft soil model underestimates the immediate settlement by about 30 % and gives excellent results for predicting consolidation settlement. The total settlement of shallow raft foundation rested on a clay layer of depth three times raft width to one time was increased by about 66 %. The consolidation settlement is much higher than the immediate in clayey soils, however, the average of immediate to consolidation settlement is equal to 0.3 % for pressure 20 kPa, and increases with rising applied pressure until it reaches 1.2 %. The numerical analysis revealed a lower value than the calculated using the theoretical equation for immediate settlement, while for consolidation settlement, the results are close except for the soft clay condition cu = 20 kPa.
