Abstract

The stress, strain and stability of slope would be changed if an Electricity transmission tower built on loess slope. In this paper, the distribution of stress, strain characteristic and stability of loess slope in condition of 30 meters height and 45 °slope triggered by action of Electricity transmission tower should be studied, the result shown that stability of loess slope dominated by the initial stress states, elastic modulus, and Poisson's ratio, strength and shape, structure and load condition etc. the stability distance of transmission line tower be located on loess slope governed by the stability of initial slope and the effect range triggered by tower load, in condition of 30 meters height and 45 °loess slope, the stability distance nearly 20m to 25m.

Abstract

The light transmitting cement mortar is to rely on a large number of optical fiber embedded in the block transferring light from the light side surface to the dark side. In this article, the preparation method of light transmitting cement mortar (LTCM) was introduced and the strength and light transmitting properties of LTCM were tested too. The results show that the LTCM can get higher light transmitting ratio and can also achieve, even exceed the light transmitting ratio of the 70g A4 print paper in the light wavelength range of 520~630nm.

Abstract

The light transmitting cement-based material (LTCM) is a kind of light transmitting new materials. A large number of optical fiber was embedded in the block and transfer light from the light side surface to the dark side. While at present, the composition, structure and performance of LTCM have been reported rarely. The paper studied the preparation method, light transmitting property and compressive strength of LTCM with optical fiber embedded by means of parallel arrange. The results show that, LTCM gets higher light transmitting ratio with appropriate optical fiber filamentous by means of parallel arrange along the light direction. This kind of LTCM can also achieve, even exceed the light transmitting ratio of the 70g A4 print paper in the light wavelength range of 580~640nm.The light transmitting ratio increases and the compressive strength decreases along with the increase of the optical fiber content in volume.
