$1 \frac{63}{64}$
8.【Solution】 $1+\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}+\frac{1}{32}+\frac{1}{64}=1 \frac{63}{64}$ (meters).

Answer: The total length of the seven bamboo poles is $1 \frac{63}{64}$ meters.

【Another Solution】We can consider it this way: Take a 2-meter long bamboo pole, cut it in half, each half being 1 meter long. Take one of the halves as the first bamboo pole. Cut the other half in half again, and take one of the halves as the second bamboo pole. Continue this process, and when you cut the seventh bamboo pole, the remaining piece of bamboo will be
$$
\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2}=\frac{1}{64} \text { (meters) }
$$

Therefore, the total length of the seven bamboo poles is 2 meters minus the length of the remaining piece, which is ${ }^{2}-\frac{1}{64}=1 \frac{63}{64}$

Answer: The total length of the seven bamboo poles is $1 \frac{63}{64}$ meters.
