Here we will describe the types & causes of horizontal cracks in the mortar joints of a concrete block wall or foundation wall that is damaged during original construction, typically during backfill. The page top photo shows a combination of open mortar joint in the block foundation wall and s...
As a result, the conflict only appears resolved, and we draw attention to both vertical and horizontal cracks in the foundation of Kadyrov's rule that could lead to renewed violence. Vertically, the Chechen strongman and his growing clout in regional and federal politics have antagonized Russian ...
the cracks occurring about the beolmaybe a prediction of initial failure of the dams,the cracks develop and progagate into the rock foundations as the water level rises.Hence,it is necessary to chock the sta- bility of cracks with the help of fracture mechanics,which is retarded as an ...
Coal is a kind of rock with the characteristics of soft structure, developed joints, cleats, cracks, and pores, resulting in that its mechanical behaviors are highly sensitive to stress, pore coalbed methane (CBM, gas) pressure and temperature. Thus, due to the variations in stress, pore pres...
Specimens primarily cracks along its bedding planes, meanwhile, elastic modulus and Poisson's ratio on the direction of vertical bedding are smaller than those paralleled to bedding planes, and anisotropic characters tends to be more remarkable for dynamic elastic parameters. Fjær and Nes (2014)...
(Spiridonoff 194; Huisman1972). During construction, a rubber “sand line” was inserted into the pipe to block the screen slots, allowing water and aquifer material to enter only through perforations in the tip (pilot). From there, water and sand were transported to the caisson through an ...
The foundation pit bottom is located in the silty clay of layer ⑤. The retaining system includes a diaphragm wall and a trench-cutting remixing deep wall, together with internal support. Dewatering, drainage, and water proof measures are adopted to control ground water. The surrounding ...
Using the symmetry in the layout of the HDPE pipes, only one repeated block of the soil domain with five embedded heat exchangers (Figure 2b) was considered to decrease the computational time [13]. The coolant fluid was a 30% ethanol-water blend with a velocity and inlet temperature of ...
Using a soil improvement biotechnology based on microbial-induced carbonate precipitation (MICP) to form a horizontal water barrier in foundation pit dewatering can not only achieve a good dewatering control effect, but also control the cost and obtain good economic and environmental benefits. In this...
data to calculate the lateral ultimate bearing capacity of gravelly soil considering the slope gradient factor. The research results developed the theory of foundation design for building structures, promoting the reliability evaluation of pile soil systems towards a more scientific and rigorous direction....
