BEARING CAPACITY CHARACTERISTICS OF COMPACTED SOFT ROCK MATERIALS

Swelling Characteristics of Compacted, Expansive Soils

Abstraet-The limitations of existing methods for the prediction of swelling behavior of compacted softs are examined. Both the purely theoretical approach and the purely empirical approach are found to be inadequate. The present study is based on a semi-empirical approach in which a model of swelling behavior is developed leading to equations relating swelling potential or swelling pressure of ...

Experimental studies on the effects of bolt parameters on the bearing characteristics of reinforced rock

Roadways supported by bolts contain support structures that are built into the rock surrounding the roadway, referred to as reinforced rocks in this paper. Using physical model simulation, the paper investigates the bearing characteristics of the reinforced rock under different bolt parameters with incrementally increased load. The experimental results show that the stress at the measurement po...

Blinking Characteristics and Corneal Staining in Different Soft Lens Materials

Background Contact lens (CL) wear can cause changes in blinking and corneal staining. Aims and Objectives To determine the effects of CL materials (HEMA and SiHy) on spontaneous blink rate, blinking patterns and corneal staining after 2 months of wear. Methods Ninety subjects in 3 groups (control, HEMA and SiHy) were assessed at baseline and 2-months. Blink rate was recorded using a video camer...
