西北干旱区土建筑遗址加固概述

西北干旱区土建筑遗址很多, 有些还是世界文化遗产。由于风蚀风化作用强烈, 西北干旱区大批的土建筑遗址已破坏严重, 因而开展土建遗址加固研究十分必要。钾水玻璃 (PS)是一种水溶性的无机胶结加固材料, 本文全面详尽地总结了PS加固土建筑遗址技术, 就加固机理作了初步探讨。认识到PS是西北干旱地区土遗址加固的一种有效方法, 可达到较理想的加固效果。

A BRIEF OF REINFORCEMENT OF EARTHSTRUCTURE SITES IN THE ARID AREAS OF NORTHWEST CHINA

There are many earth-structure sites in the arid areas of Northwest China, some of them are world cultural eritages. But it is regretful that they were eroded and deflated under the specific climate in the areas and damaged are very seriously. It is fairly necessary to study reinforcement of the earth-structure sites. Potassium silicate is an inorganic cementing-reinforcing material of aqueous solution. In this paper, a reinforcing technique for ancient earth-structure sites is described in detail and the mechanism for the reinforcement is preliminarily discussed. On the bassis of our practice, we conside that the potassium silicate is an effective material for reinforcement of earth-structure sites in the arid Northwest China and has an ideal effectiveness. It should be put into practice in the future.
