基于VISUAL BASIC 2005的土钉支护程序设计开发摘要
土钉支护技术在工程中积累了丰富的实践经验,而理论研究方面相对落后。由于大量基坑工程集中在市区,施工场地有限,施工条件复杂,基坑支护不仅要保证基坑结构自身安全,还要保证邻近建筑物和市政设施的安全和正常使用,所以在土钉支护设计时要进行详细的且比较复杂的设计
和计算,包括土钉抗拔承载力、内部整体稳定性、抗滑移稳定性、抗倾覆
●
稳定性等。而在实际应用中,用于辅助土钉支护设计计算的软件相对较少, 大部分土钉支护工程采用经验值来设计、采用手算来验算土钉支护的安全稳定性,这无形中增加了工程设计人员的计算工作量,也增加了土钉支护设计的不可靠性和不安全性。
出于对以上实际情况的考虑,本文意欲在土钉支护设计计算软件开发方面做一些努力,以工程中通用的土钉支护技术规程为理论依据,采用 VISUAL BASIC软件开发工具,开发出一套有可视化界面的土钉支护设计计算程序。

该土钉支护设计计算程序主要能完成以下几方面的工作: (1)基坑土体地质参数的采集和储存; (2)土钉支护参数的采集和储存; (3)各种工况下土钉侧压力计算; (4)土钉抗拔承载力计算; (5)士钉支护内部整体稳定性分析; (6)土钉支护抗滑稳定性分析; (7)土钉支护抗倾覆稳定性分析。
作为土钉支护设计计算辅助工具,该软件经过测试,计算结果稳定可靠,能有效的提高土钉支护设计计算效率和准确性,帮助工程设计人员脱离繁琐的设计计算,为土钉支护设计提供辅助计算和参考。

APPLICATIoN OF VISUAL BASIC 2005 FOR THE DESIGN AND CALCULATION SoFTWARE oF SoIL NAILING
ABSTRACT
With the high development of modern architecture and urbanization and the increasing scale and hight of the buildings,the foundation’S excavation es deeper and the supporting of foundation is ing a hot and difficult issue in the projection of high buildings and receives more concern among the fields of academy and also many new techniques and e forth in engineering field of deep foundation pit supporting, among which,soil nailing is a safe,reliable and economical technique in the
engineering practice.
The engineering practice of soil nailing is very abundant,but theories and research of this technique is relative many foundation engineering projects are constructed plex conditions in urban areas,and the working site is limited,and the supporting of foundation must ensure the safety of both itself and the nearby buildings,therefore,in the designing of soil nailing plicated designs and calculations must be made such as that of the bearing capacity,internal stability,sliding resistance and tilting resistance. However,in the practice the design and calculation software about soil nailing is
