台湾车笼埔断层深井钻探计划(TCDP)概述

Summary of Continental Scientific Drilling Program(TCDP) in Taiwan

台湾车笼埔断层深井钻探计划(TCDP)是台湾车笼埔断层上进行的科学钻探工程。该计划于2004年开始实施,拟通过深达2 000 M的钻探,获取台湾1999年集集MW7.7地震深部断层带的岩芯样本和流体观测资料,并通过一系列的深井探测和观测研究,分析车笼埔断裂产生剧烈错动的原因。本文介绍了台湾车笼埔断层深井钻探计划(TCDP)的基本情况,论述了TCDP项目的科学假设、工作计划、合作项目以及近期的进展。全面了解TCDP相关内容,对我国大陆进行地震研究和深井钻探工作具有重要借鉴意义。

The Taiwan Chelongpu-fault scientific drilling program（TCDP） was put in practice in 2004. This program would drill a 2000 m deep hole on the Chelongpu-fauh. The significance of this program is to obtain a physical sample of the fault where large displacements occurred during Taiwan Chi-Chi earthquake in 1999, to measure the physical properties and mechanical behavior of the rocks and fluid of the fault zone and to thoroughly understand the state of stress that exists in these rocks following such a large slip event. This paper has introduced the basic condition of TCDP, and elaborates on related contents, such as scientific supposition, work plan, cooperation project and recent progress. To realize the TCDP is useful to us for future seismic investigation and fault drilling.
