摘要

自行走式隧道掘进机是一种新研发的非开挖技术装备，其克服了盾构和顶管长距离施工受限和急转弯不够灵活的缺点。为设计和制造自行走式掘进机应用型工业样机提供参数支持，通过设计和加工小型样机，先后进行模型试验和现场试验，得出增阻块提供的推力与增阻块撑出时在管轴垂直方向的投影面积为近似正比例关系。

Abstract

The selfdrive tunnel excavating machine is a newlydeveloped trenchless technology equipment, which overcomes the shortcomings of shield machines and pipe jacking method, such as limiting of long distance boring and inflexible sharp turn. In order to provide parameter support for designing and manufacturing industrial prototype of selfdrive excavating machine, a miniprototype is designed and manufactured and model test and field test are carried out. The relationship between increased resistance of excavating machine and launchingout area of resistant block approximates positive correlation.

Key words： selfdrive excavating machine; increased resistance; resistant block; field test; model test; launchingout area of resistant block
