根据《混规》第6.3.4条
$$
V \leq \alpha_ {\mathrm{cv}} f _ {\mathrm{t}} b h _ {0} + f _ {\mathrm{yv}} \frac {\mathrm{A} _ {\mathrm{sv}}}{\mathrm{s}} h _ {0}
$$
$$
h _ {0} = 6 5 0 - 4 0 = 6 1 0 \mathrm{mm}
$$
$$
3 7 0 \times 1 0 0 0 \leq 0. 7 \times 1. 4 3 \times 2 5 0 \times 6 1 0 + 3 6 0 \times \frac {\mathrm{A} _ {\mathrm{sv}}}{\mathrm{s}} \times 6 1 0
$$
$$
\frac {\mathrm{A} _ {\mathrm{sv}}}{\mathrm{s}} \geq 0. 9 9 \mathrm{mm} ^ {2} / \mathrm{mm}
$$
选项(D)满足 $\frac{\mathrm{A}_{\mathrm{sv}}}{\mathrm{s}} = \frac{78.5\times 2}{150} = 1.05\mathrm{mm}^2 /\mathrm{mm} > 0.99\mathrm{mm}^2 /\mathrm{mm}$
因此选(D)
