Perkuatan Lereng pada Sempadan Sungai Jl. Sultan Agung Kabupaten Jember dengan Dinding Penahan Tanah Kantilever

The land collapsed on Jl. Sultan Agung, Jompo, Jember Regency was reported. A team from the Regional Disaster Management Agency (BPBD) found cracks in the ground under a shop since February 2019. This incident resulted in a landslide of a road with approximately 45 meters long and 10 meters wide that it blocked the river flow, and nine shophouses, which are the assets of the Jember Regency government, collapsed as deep as approximately 4 meters. The cantilever type retaining wall is designed in the landslide area as an effort to revitalize the banks of Jompo river on Jalan Sultan Agung. Cantilever wall design stability refers to SNI 8460: 2017 and was assisted by using the GEO 5 program. The stability of cantilever walls against overturning shows a safety factor value of 3.72 that greater than 2 (safe condition), whereas the stability of cantilever walls against sliding was 1.61 that greater than 1.5 (safe condition), and the stability of the bearing capacity was 8.18 that greater than 3 (safe condition). Cantilever wall structure using concrete quality (Fc ') 40 MPa, and reinforcement quality (Fy) 420 Mpa, with a diameter and a distance of 25 mm and 125 mm respectively. Additional reinforcement was given to the Cantilever Wall, i.e. a bore-pile with a diameter of 60 cm which was fixed to a depth of 6 meters.

A Study on the Quality Assessment System of Substructure Reinforcement Method

For substructure reinforcement method, corresponding quality assessment system is established based on analytic hierarchy process (AHP). At the same time, the actual application process of the system was found. Structure of judgment matrix, synthetic weight and for each layer of element and fuzzy comprehensive evaluation was figured out. Finally, the system is verified by practical engineering. Something is obvious as the result shows. Firstly, the comprehensive assessment system for reinforcement quality of bridges is reasonable and practical. Secondly, this system takes some advantages to the systematization, standardization and theorization for the assessment to reinforcement quality of bridges.

A Study on the Quality Assessment System of Reinforced Concrete-Skein Reinforcement Method to Arch Bridges

For reinforced concrete skein method to arch bridges, corresponding quality assessment system is established based on analytic hierarchy process (AHP).

Local Response Rates as Affected by Reinforcement Quality

Four white rats were trained to bar press on reinforcement schedule Tandem FI 30 sec. FR11, a procedure intended to approximate a runway situation with intertrial intervals of at least 30 sec. Means and distributions of times taken by Ss to make 10 responses were approximately equal irrespective of reinforcement quality over the range 0 to 32% sucrose by weight in water. Similiar results were obtained with two other Ss reinforced on schedule FR12, 5-sec. delay, and with another reinforced on schedule FR24. The results were interpreted as showing that reinforcement quality affects competing behavior rather than response speed when S is responding.
