This study used OWAS to analyze the working postures of construction workers on building the foundations of a log cabin. Three construction workers, with an average work experience of 40 years, participated in this study. Eight elementary jobs of building the foundations of a log cabin were videotaped at a construction site and analyzed later in the laboratory. For an overall distribution of tr...

Abstract In order to improve the accuracy of calculation method bearing capacity prefabricated pier connected by grouting bellows, formula ultimate assembled bridge piers with corrugated pipe connection under action bi-directional compression and bending is deduced. Firstly, quasi-static testing cast-in-place unidirectional loading are introduced, capacities compared. Secondly, according arrang...

Owing to the increasing applications and popularity of grouting reinforcement technology for water control in mine floors, its effect is becoming increasingly concerning. However, lack an effective evaluation method floor composite limestone aquifers under different treatment modes can lead blindness randomness engineering. Thus, based on engineering practices, we analyzed prevention inrush fro...
