Abstract

Rainfall infiltration is an important factor affecting the stability of the ancient city wall. To state the wall line spring door where, for example, soil temperature and humidity sensor, the earth pressure meter and rain gauge carried out such as rainfall, volume moisture content and soil pressure monitoring, analyzed the inner core wall soil volume moisture content and soil pressure response law of rainfall different rainfall conditions is studied through numerical simulation method the stability of the ancient city wall. The results show that :(1) rainfall has a significant effect on the volume moisture content and earth pressure of the inner core soil;(2) The response to rainfall is different at different depths of the city wall, and the response to rainfall in the middle part of the city wall has a certain hysteresis;(3) Compared with the low-intensity and long-duration rainfall, the high-intensity and short-duration rainfall has a greater impact on the stability of the city wall. The research results have certain guiding significance for the protection and monitoring of the ancient city wall.

基于原位监测的古城墙降雨入渗分析及影响——以丽水州杏春门为例

降雨入渗是影响古城墙稳定性的重要因素。以国墙线弹簧门所在的土壤温湿度传感器、土压力计和雨量计等进行了降雨量、体积含水率和土压力的监测，分析了内心墙土壤体积含水率和土压力对降雨不同降雨条件下的响应规律，通过数值模拟方法研究了古城墙的稳定性。结果表明:(1)降雨对内芯土的体积含水率和土压力有显著影响;(2)城墙不同深度对降雨的响应不同，城墙中部对降雨的响应有一定的滞后性;(3)与低强度、长持续时间降雨相比，高强度、短持续时间降雨对城墙稳定性的影响更大。研究成果对古城墙的保护与监测具有一定的指导意义。

期刊介绍： International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.
